Give the McCain camp credit. They're pretty upfront with what McCain's new mortgage-buy-up plan is really all about.

From the McCain campaign website (emphasis mine):

John McCain will direct his Treasury Secretary to implement an American Homeownership Resurgence Plan (McCain Resurgence Plan) to keep families in their homes, avoid foreclosures, save failing neighborhoods, stabilize the housing market and attack the roots of our financial crisis.

Incidentally, as a reader points out, isn't this the third different mortgage relief "plan" McCain has announced this year?
