Obama's money problem

In writing about Santorum's recent victory, Ezra Klein makes an important observation about Obama's financing:

On Tuesday, there was a lot of talk about President Obama's decision to embrace the need for Democratic superPACs. The decision was born out of necessity, and even so, it may fail to solve Obama's money problem. Wall Street, which aggressively funded Obama in 2008, has turned on him. Hollywood, which is reliably Democratic, is nevertheless furious that the White House helped kill the anti-internet piracy bills SOPA and PIPA. There are still trial lawyers, and unions, and assorted other wealthy folks and interests, but there's a real question as to whether a Democrat who wants to tax rich people and regulate big industries can match the financial firepower that's backing Romney's campaign.

Of course, as Klein correctly indicates in the rest of his post, Santorum's victory illustrates the relative unimportance of the money candidates spend on their campaigns. Aside from anything else, the cost of propelling Senator Obama to presidential level in the public's mind won't be quite the same given that it has been President Obama for some time now. When voters reach the ballot box, such things simply don't matter.
