Politico's Ben Smith has the goods, as well as the above photo:

The beleaguered Democratic-leaning community group Acorn sends over this photograph: John McCain, in March of 2006, sitting beside Florida Rep. Kendrick Meek at an event Acorn co-sponsored in Florida.

The immigration event, which other photos show was packed with red-shirted Acorn member, was co-sponsored by the local Catholic Archdiocese, the SEIU, and other groups.
