I haven't seen much in the news about what's going to change when Republicans control the US senate except for one headline saying Republicans were meeting to decide what to do next. I didn't read the story but it was probably a short meeting. After voting unanimously to "Come out against everything the black man is for" they adjourned and went to play tennis with their mistresses.
I don't expect change in New Mexico, either. Democrats newly aware of how important their base is will rise up to oppose the more draconian policies of the governor, and the ones who endorsed the governor will veer off the road one night to avoid a giant image of San Ysidro.
