Brownback lays into Romney

Brownback really whacks him:

Mitt Romney is a good man. But there are many differences between us on the issues. I am for a three state political solution in Iraq. He is not. I am pro-life. He is not. I am opposed to gun control. He has not been. I am for a flat tax. He is not

Recall that Romney had actually taken out an ad in 1996 against Forbes’ flat tax proposal.
