New Mexico Gov. Susana Martinez recently lost her bid to deny driver's licenses to undocumented immigrants. The bill died in the state Senate, and Martinez, whose state is one of only three to allow undocumented immigrants licenses in the first place, has vowed to fight on. The story of the licenses is interesting on its own: Reuters reported that over 80,000 foreign nationals hold licenses in the state, and revoking those could put New Mexico right in the middle of the national immigration debate.
