The Politico has an interesting story about how immigration and its politics may be shaking up conventional Democratic and Republican coalitions. It also has a survey of five races in which immigration may be a campaign issue: a Republican challenging a Democrat as "weak" on enforcement, a Democrat challenging a Republican as "weak" on border security, one Republican potentially challenging another (Chris Cannon, a famous proponent of "comprehensive immigration reform"), and a PA race in which Lou Barletta (R) (of Hazleton fame) may challenge a 20-year Democratic incumbent. Then, there's this interesting race:

Democratic Rep. Ciro Rodriguez, usually a liberal stalwart, was the only member of the Congressional Hispanic Caucus to back a tough-on-immigration proposal earlier this year.

That’s probably smart politics in a West Texas district that gave President Bush 57 percent of the vote in 2004.

But it could also come back to bite him politically in a district that is nearly two-thirds Hispanic. Rodriguez’s likely Republican opponent is self-funding businessman Quico Canseco, who wants tough enforcement measures to battle illegal immigration.

Canseco sounds very skeptical of the "grand bargain," and his website says this about "immigration" (which is at the top of his list of "issues"):

Immigration: We take great pride that our country is one of a few in the history of the world where people are trying to get in instead of out. We are a bastion of freedom and liberty composed of a population of immigrants from all over the world. The success of America is its constitution, its laws and its common language. When we begin to discard one or the other of these tenants of our society, we tear away the very fabric of what has guaranteed our national survival. As a nation, we must not condone illegal entry into our country. We must take all measures to secure our porous border, and to protect our nation’s sovereignty. America is a welcoming nation and it should continue to extend a warm welcome to those that want to enter in accordance with the laws, the rules and the regulations for entry. Those that do so otherwise disrespect our nation’s sovereignty and they must not benefit by their illegal trespass.
