ABC News’ Rick Klein reports: With Rodney Glassman trailing in polls against Sen. John McCain, R-Ariz., the Democratic candidate for Senate in Arizona is taking to song to try to oust the longtime incumbent. Glassman became a YouTube mini-sensation with his rendition of “Sweet Home Arizona,” where he argues — and shakes his hips along the way — that it’s time to end McCain’s career. On ABC’s “Top Line” today, he was generous enough to sing us a few bars. “Sweet home Arizona, where the skies are so blue; sweet home Arizona, John it's time to retire you,” Glassman sang. When he wasn’t singing, Glassman made his case for why the polls might be off, saying his campaign will close with visits to Arizona’s biggest population centers “People are tired of the mud-slinging, and that's what McCain has become known for,” Glassman said. “Arizonans know that after 30 years in DC, he is the federal government,” he added. “You can get rid of SB1070 [the state's controversial immigration law], you can get rid of all the other issues going on, but at the end of the day, we need to retire McCain. We need to have a senator working in DC on federal immigration reform, because every Arizonan knows that it's the federal government’s responsibility to take care of it. It's very simple.” And the singing, he said, will continue, so long as it helps draw attention to his campaign: “I'll sing it but I want everyone to go to our Web site RodneyGlassman.com and learn more about all of our issues,” he said.
