Will Colin Powell Endorse Obama or McCain this Sunday? Political World Is Holding Breath

ABC's "The Note" just included this:

TiVo alert:

Colin Powell appears Sunday on "Meet the Press"

Being endorsed by Powell is up there with being blessed by Mother Theresa or walking toward the ocean with Gandhi.

As Politico's Mike Allen reports, NBC’s ‘Andrea Mitchell broke the news of Powell’s surprise “Meet the Press” appearance on the “Today” show this morning.

As Allen notes, Powell has served the last three Republican presidents. Whether he endorses Obama or McCain, the news will be huge.

Powell’s unassailable national security credentials could sway voters who are vacillating about whether Obama is ready to be commander in chief, and his endorsement of the Illinois senator would make a national security emphasis by McCain in the election's closing days extremely difficult.

Powell, 71, a professional soldier for 35 years, has advised the last three Republican presidents.

The general’s camp is being coy about what he might or might not say on Sunday. But some McCain advisers suspect, without being sure, that Powell will endorse Obama.

“It’s going to make a lot of news, and certainly be personally embarrassing for McCain," a McCain official said. "It comes at a time when we need momentum, and it would create momentum against us.”

I know what I'll be doing Sunday morning.
