If he decides to be on McCain's ticket, or endorses McCain, the GOP has a chance at the White House.

Powell Far More Likely than Obama to Beat McCain
Monday, August 25, 2008

It’s a good thing for Republicans that Colin Powell is still one of them.

Powell, the popular former secretary of state and chief of the Joint Chiefs of Staff, handily beats Republican presidential candidate John McCain in a one-on-one match-up. This comes at a time when Barack Obama holds a very slight lead over McCain in the Rasmussen Reports daily Presidential Tracking Poll.

Powell, the best-known African-American in the Republican Party, beats McCain more than two-to-one, 54% to 26%, with 21% of voters undecided.

An identical number of Democrats (75%) prefer either Obama or Powell over McCain.
But while 84% of GOP voters favor McCain against Obama, just 48% favor him over Powell, who pulls 35% of GOP voters in a contest with his fellow Republican.


Unaffiliated voters give the edge to McCain over Obama 41% to 35%. But Powell beats McCain among unaffiliateds 44% to 21%.



But, if Powell endorses Obama, (which is quite possible) is McCain toast?
