Video: Davis said he no longer recognizes a Democratic Party that now preaches full reliance on government aid and welfare.

Arguably one of the most infectious speeches of the night at Tuesday�??s Republican National Convention was given by a man who admitted he had been playing for the wrong team during the last political conventions.

Former Alabama Congressman Artur Davis, who changed his party affiliation from Democrat to Republican this year after delivering a 2008 speech at the Democratic National Convention, said President Barack Obama�??s first term had showed him the error of his ways.

�??Maybe the Hollywood stars and the glamour blinded us a little: you thought it was the glare, some of us thought it was a halo,�?� Davis joked.

In spite of hopeful promises, Obama�??s America has yielded joblessness and poverty, said Davis.

�??Dreams meet daybreak,�?� he said.

While Davis stood by the Democratic party of yesteryear, with heroes in John F. Kennedy and Lyndon B. Johnson, he said he no longer recognizes a party that now preaches full reliance on government aid and welfare rather than self-sustainability.

�??You know, the Democrats used to have a night when they presented a film of their presidential legends: if they do it in Charlotte, the theme song should be this year’s hit, ‘Somebody That I Used to Know,�??” Davis said, referring to a popular Gotye song.

Well, he said, lesson learned. This year was the time to make it right.

Tuesday night wasn’t the first time politicians have crossed over parties to address conventions. Most recently, Georgia Democrat Zell Miller gave a rousing speech to Republicans in 2004. Democrats will have a chance to hit back at Davis next week, however, when they welcome ex-Republican and former Florida Gov. Charlie Crist to address their convention in Charlotte, N.C.
