Only one campaign debate is left, just 20 days remain and the two presidential tickets are furiously fighting down to what could be a photo finish. It's time to bring in the closers and amp up the patriotic music.
President Barack Obama's campaign is enlisting rocker Bruce Springsteen, 62, whose 1984 song "Born in the U.S.A." is one of his best-known and most frequently performed singles.
Springsteen will make a joint appearance with former President Bill Clinton on Thursday at a Democratic rally — minus Obama — in Parma, Ohio. Springsteen will also appear at a Democratic campaign event in Ames, Iowa, later Thursday.
Mitt Romney's GOP campaign is bringing back veteran country singer Lee Greenwood, 70. His rendition of "God Bless the USA"— with a chorus that includes "Proud to be an American" — has graced many GOP events since the days of Ronald Reagan.
Greenwood was performing at a Romney rally Wednesday in Chesapeake, Va.
Other pop culture figures are also lending their voices.
Romney has Detroit rocker-rapper Kid Rock, whose "Born Free" is used repeatedly by the ticket on the campaign trail
Meanwhile, rapper Jay-Z, his wife Beyonce and rock musician Jon Bon Jovi are helping Obama.
After their lively and often confrontational second debate, both candidates and their running mates were attending day-after battleground-state "victory" rallies Wednesday — Obama in Iowa and Vice President Joe Biden in Colorado; Romney in Virginia and Rep. Paul Ryan in Ohio.
"Didn't Mitt Romney do a great job for us last night?" Ryan asked to cheers in Berea, Ohio. Just as in the first debate, "we saw a leader," he said.
Biden, making the rounds of morning TV shows, said the more assertive, self-assured Obama many Americans saw Tuesday night "is the guy I see every single day."
