The difference between Obama and McCain is that McCain actually had AIG lobbyists on his staff...
Secondly - These contributions came from employees at all levels and were cut off at something like $2400 max - due to campaign finance laws... no big deal, really.
It's really shady for Republicans to make it sound like Obama accepted lobbying money from AIG as a corporation... That's a lie.
He recieved more donations from lower-level workers than any other candidate.
