From onstage shout-outs to a cover story in one of music's most lauded publications, the presidential race continues to garner attention from the music world. The latest artists and icons stepping up and speaking out below.

• George Clinton brought funk and campaign fervor to both Sum Funk 2008 and Detroit's Comerica Cityfest, where he endorsed Barack Obama with words and and an ornate tshirt.
  
• Rolling Stone editor-in-chief Jann Wenner took his support for Obama to the brink by giving him the cover. Again. The Illinois senator first graced the face of RS back in March, and was positioned as "A New Hope." This month, in an attempt to send an even stronger message, the cover bears no words at all.
• While Obama has denied having correspondence with starlet Scarlet Johansson, he has, however, reportedly been connected to Jennifer Lopez, who spoke about "health care with members of his staff."
  
• Boy George, who was denied a Visa to the U.S. and was forced to cancel his tour, penned a song for Barack Obama entitled (you guessed it) 'Yes We Can.' Hear it here.
• The National have created "Mr. November" tshirts in support of Barack Obama, with all proceeds going to his campaign. The shirt's meaning is twofold: the first is obvious, and the second refers to the last track on the band's 2005 album, 'Alligator.'
  
• Lil Wayne supports Barack Obama. He guesses. In an interview with Blender, the top-selling rapper waxed poetic on politics saying, "A woman or a black man versus an old white dude? F--- no! They gonna be like, 'This black-ass n---- trying to come in my Oval Office? F--- no!'"

With Barack Obama campaigning full-steam ahead as the Democratic candidate for this year's election, the contest for Commander in Chief has become a bit more focused. So we, too, carry on and keep watchful eye of all things 2008 election. Here's the latest:

• Scarlett Johansson revealed that she and long-time political idol Barack Obama are having an email affair of sorts. The blond bombshell, who is in constant contact with the senator, defended herself saying, "If the spotlight is on me, I might as well try to direct it on things and causes that I believe in."
• Although Chuck Berry's 1958 hit 'Johnny B. Goode' surfaced as one of John McCain's campaign songs this year, Berry calls himself an Obama man. "It's no question," he said of his support for the Illinois senator. "Myself being a man of color ... I mean, you have to feel good about it."
• Nas has responded to Obama's all-but-official nomination with 'Black President' -- a track he recorded that includes a snippet of Obama's 'Yes We Can' speech.
• Speaking of that speech, there is now a Spanish version of Will.i.am's once ubiquitous, now annoying video endorsement of Obama. Go to PodemosConObama.com to see the version of 'Yes We Can,' which features artists like Paulina Rubio, Don Omar and Alejandro Sanz.
  
• Is the Barack Obama presidential campaign at the center of a "tough twee" musical movement? Have cardigans and sweets been replaced by an angrier sort? Discuss.
• This list presents 12 cultural instances that helped Barack Obama win the ticket. No. 3 involves 'Sesame Street.'

As rumors swirl that Hillary Clinton may, in fact, bow out of the battle for the Democratic ticket soon, we'd like to take a look back on the past couple of weeks to see who's been speaking up, rocking out and getting down for their personal political views. Here is the latest ...

• The Flaming Lips' enigmatic frontman, Wayne Coyne, took several opportunities at this year's Sasquatch! festival to empower his audience. During the band's headlining UFO Show performance Coyne called for change this November and addressed the crowd, "Come on motherf------!" He not only spoke to the seriousness of the situation in Iraq, but also interrupted the show to play 'Taps.'
  
• Sasquatch! produced several more political moments, including when guitarist Mike Clark from Stephen Malkmus & the Jicks told the crowd that they were "still holding out for Hillary." Then there was Michael Stipe who, barefoot during R.E.M.'s rainy set, asked, "Who thinks Barack Obama is the coolest guy in the world?"
• The Decemberists jumped on the rock-for-Obama band wagon when they held a free concert in Portland, Ore., before the candidate's recent rally.
  
• Outspoken Everclear frontman Art Alexakis maintains that 'Jesus Was a Democrat' in a new single his band is set to record in response to their opposition to the war. "I think that a lot of people who call themselves Christians would think -- if Jesus came back today -- that he's a terrorist because he isn't blond-haired or blue-eyed," he told Spinner. "Those are the people we're trying to kill."
• During an interview with Spinner, Mick Jones said that he wants "anybody but McCain" to win this year's presidential race. He continued, "My real dream ticket would be Jed Bartlet (Martin Sheen in 'The West Wing') with the vice president being the guy from '24,' Dennis Haysbert."

• Sean Penn took advantage of his Coachella time to preach volunteerism before My Morning Jacket's set. "Revolution is a young man's job," he said. "And you can be the revolution!" Oh, and he also hung out with Sienna Miller. A lot.
  
• Hillary Clinton launched Project T-Shirt. It's a design contest. And, like, if your design wins, you'll get a photo of both daughter Chelsea and Hillary rocking the thing ... in public!
  
• As previously reported, Arcade Fire and Superchunk planned to rock for Barack. And they are! Here's proof.
• 'The Hills' star (and wannabe pop singer) Heidi Montag says she's firmly planted in the John McCain camp. McCain answered, "I'm honored to have Heidi's support and I want to assure her that I never miss an episode." Barack Obama took the comedic approach to her (ir)relevance.

The latest ...

• Against Me! made a public service announcement that urges people to "Stop! Take some time to think/Figure out what's important to you." It's kinda catchy.
  
• The Roots' ?uestlove gushed about Barack Obama. "He appeals to the hopeless romantic in all of us," he told Spinner. "But I don't want people to misconstrue Obama's hope for a winning lottery ticket. If people see Obama as the lottery ticket that will instantly solve their problems, I'm sorry, but that's not going to happen. A lot of the political changes is gonna happen within these people themselves."

Since the beginning of the race, the flip-flopping lead between Senators Barack Obama and Hillary Clinton have had political analysts gleefully marveling at the record-breaking turnout in state primaries. But after a recent big run from the Obama camp, it's down to the wire for Clinton this Tuesday, March 4, when primaries in Texas and Ohio may very well seal the fate of the former first lady, who trails her opponent by more than 100 delegates.

And so, the battle surges forward. If there's one thing that's certain about this year's Democratic race, it's that America really cares this time around. Not only has John Q. Voter stepped up to the plate, but many musicians have voiced their allegiances this year, which has us noticing some trends. For example, seasoned divas are pulling for homegirl Hillary. Madonna, Cher, Janet Jackson and Carole King have all sided with the former first lady. Meanwhile, rockers seem firmly planted in the Obama camp, with names like Fall Out Boy's Pete Wentz, Morrissey, Jeff Tweedy of Wilco and Win Butler of Arcade Fire Baracking out.

Last week ...

• First, John Mellencamp asked John McCain to cease and desist his use of 'Our Country' and 'Pink Houses.' And now the GOP leader has run into trouble with ABBA. "It gets expensive in a big hurry," he said after formally dropping the Swedish legends' 1977 hit 'Take a Chance on Me' from his campaign trail playlist.
• Dave Matthews is rumored to be playing an Obama rally for the Bobcats on March 2. According to Ohio University's Vice President of Student Affairs, the college rock king is likely to play at Athens' Convocation Center, but sans the presidential hopeful.
  
• Speaking of Obama rallies, watch Bright Eyes and M. Ward duet in the name of Barack.
• Neil Young voiced his respect for George Bush. Sort of.
• Oh, and Ralph Nader joined the race. Better late than never? We're not sure.
