John McCain's (R-Ariz.) Senate re-election campaign got a boost Wednesday from former Florida Governor Jeb Bush, who endorsed the Arizona Republican.

"As we continue to face tough challenges both at home and abroad, America needs leaders like Senator John McCain in the United States Senate," Bush said. "John is a proven conservative leader committed to reducing taxes, fighting wasteful spending and keeping America safe."

Jeb Bush joins a list of conservative superstars backing John McCain's tough primary battle against former Arizona congressman and popular talk show host J.D. Hayworth. Among those on the list: potential presidential contenders former Massachusetts Gov. Mitt Romney and former Alaska Gov. Sarah Palin, Minnesota Gov. Tim Pawlenty, and fresh-faced champions of the right, Sen. Scott Brown of Massachusetts and Gov. Bob McDonnell of Virginia.
