Colin Powell to Endorse Obama at Convention?

Update: "sources" say that Powell likes McCain but hasn't found a reason to vote for him yet. 

This is coming from Fox and Bill Kristol, who originally named Tim Kaine as Obama's veep, and who is anti-Obama. Kristol says Powell may give the keynote speech on veterans and national security. Wow.

This is a big endorsement if indeed it's true.

I can't tell you how many wingnut blogs I've read where the blogger states they hate Obama because of whatever (take your pick) but would vote for Colin Powell in a heartbeat. How would they respond to a Powell endorsement?

At CNN, Powell's office has denied that he's made an endorsement decision.
