A strongly socially conservative Republican (except for an immigration hardliner) won't be winning this district any time soon, Vosem.
I don't see one primarying DeMaio either
Yeah, DeMaio has an opportunity to hold on to this district for a while if he does actually win. He can continue to be moderate on most social issues except perhaps immigration. Although even there he would likely need to be in favor of more skilled immigration, which most non-crazy Republicans support anyways. Good amount of Asians (specifically Filipinos) in this district who are swing voters who voted for Obama twice and likely the reason why Bilbray lost.
I should mention that his pro-choice views could be a problem for him in the future. He is lucky he doesn't have to run in a closed Republican primary.
