A lot of Democrats are trumpeting Colin Powell's endorsement of Barack Obama, signaling the defection of someone who was once favored highly by the GOP.
However, one thing we forget, the GOP fell out of love with Colin Powell when it was discovered that his political beliefs, outside of national defense, really lines up with the Democratic Party platform much more than the Republican platform, anyway. That is the biggest reason why support for him as a Presidential candidate waned very quickly each time he has been mentioned as a potential candidate...Republicans don't like his policies on most issues that don't deal with the military and and national defense.
This will not really attract any GOP voters or conservative independents to Obama, as Powell's scope of influence has shank considerably, especially with Republicans. Most of us already knew that Powell was more of a Democrat anyway, so what's the big deal?
