Its the invoking of that old standard by Newt to raise the hackles of the bigotted on the right that pisses us off.
Educated liberals understand that the perception that there are a disproportionate number of black people on food stamps is because there are a disproportionately high number of black people who are poor.
The audience Newt aimed that comment at can't get past the initial observation, and use that observation to feed their impression that black people are lazy, undeserving of assistance, and a drain on their tax dollars.
Invoking that connection to Obama was the point of saying it. Its the same tired "He's out to help black people at our expense" theory which underlies roughly 2/3 of the entire GOP attack on him since day one.
It plays great to the people paying attention to GOP presidential politics at the moment.
so let me get this straight. your argument is that they make that connection because they KNOW the GOP people are racists and can read their minds? so you agree that the democrats are the ones bringing up the connection first.
