(Indianapolis, Ind.) - Indiana Governor Mitch Daniels is not speaking much about a possible run for the White House as speculation grows that he will do so. 

He would not say Thursday if he would step down as governor in order to run for the Republican nomination, adding he hasn't thought about that yet. 

Daniels will speak Friday night to the Conservative Political Action Conference in Washington, D.C.  The governor landed a prime-time speaking role and will be introduced by columnist George Will, adding fuel to the speculative fires that he will be a GOP candidate in 2012. 

The governor wouldn’t tip his hat to reporters.

“Listen to the speech, you know. You’ll tune it out if I tell you now,” he said, adding he will pay tribute to the president, but that wouldn’t be the central point of his talk.

Daniels has said repeatedly he won't decide on a presidential run until the legislative session ends in April.
