Via AoSHQ's headline feature, Doubleplusundead has some good news on that front. The Houston Chronicle is reporting that Lampson (D) in TX-22 is fading against Olson (R), while Culberson (R) in TX-07 is maintaining his own lead.
The NRCC has an ad out for Olsen:
...which is probably going to give Democrats fits, which is always nice. Anyway, Culberson is currently being outspent by challenger Skelly, and Texas Democrats really want this one, so by all means toss in some cash. Olson too, of course: donate here. Every little bit helps, and the more freshmen Dems they lose, the happier we're all going to be.
