Well, Arizona may just outdo itself again.

This year, their prospects have improved. A proposal to draw local police deeper into the fight against illegal immigration has momentum, and even opponents expect the new Republican governor to sign off on the changes.

The proposal would make Arizona the only state to criminalize the presence of illegal immigrants through an expansion of its trespassing law. It also would require police to try to determine people's immigration status when there's reasonable suspicion they are in the country illegally.

An estimate 460,000 undocumented immigrants live in the state.
