If someone sued me for not agreeing with them on a political issue which in this case is immigration, then I wouldn't be inclined to vote for them for re-election.
Ummm...not everyone in Arizona agrees with the legislature's immigration policy...
I'm sure not everyone does agree. For example those who are here illegally sure don't agree with it. In each state and nation you get a variance of political ideology and stances on issues. I'm talking about what the state did as a law to protect their borders though and Obama suing over it. All things being equal he's lose about 56-43.
