EJ: Money Not Growing on Trees for Prez

Four years ago, the Obama campaign had all the money it could ever want, while John McCain's funds were limited. EJ Dionne warns it won't be that way this time, and that will negate many of the advantages Obama is seen as having over Mitt Romney in November.

I think the president goes in with structural advantages. I think the big difference this time from last time is the president vastly outspent John McCain in the last election. I think this time with all that Super PAC money coming in from the right, it's going to be a real challenge to the president.
