Indiana Republicans may witness the formation of the ultimate GOP 2012 presidential ticket.

New Jersey Gov. Chris Christie (R) will be the keynote speaker at the state party's annual fall dinner on Oct. 26 in Indianapolis. He'll be introduced by Indiana Gov. Mitch Daniels (R). Both men are on the list of contenders for the Republican presidential nomination.

Christie has vehemently denied he's interested in making a White House run. But the first-term governor has been traveling widely this cycle in support of Republican gubernatorial candidates, which has fueled speculation he'll consider entering the national arena.

Daniels, meanwhile, has long been mentioned as a possible candidate. During a trip to Washington last February, he refused to rule out making a bid for the Oval Office.
