Thats because their local constituents are not happy with amnesty if thats what the President supports.
I do disagree with him on that matter but its just one of many issues that I think is important to me.
My local rep agrees with me on this issue and I dont see how sitting the elections and not voting for him will help the anti immigration problem. Last time I checked, the Rats are completly against anything we propose.
I've never sat out an election in my life -- not even a small local election. So far I'm two for three and the two decent people are up for re-election.
