Maybe Walker/Martinez. Both have records of fighting abuses of power. Walker stood up to the public employee unions. Martinez just signed a bill ending civil asset forfeiture at the state level.
Yeah, I agree, she’d be a strong running mate, IMHO the best choice. Actually wouldn’t be a bad choice of running mate for Cruz, either, although some might get cranked about an all-Latino ticket (wouldn’t bother me in the least; let’s see, I’ve been accused of being Mormon, Roman Catholic, specific individuals, so just to save time if you’re reading this, I’m about as non-Latino as anyone ever born), even the Latino Demagogic Party camp-followers wouldn’t be able to swing the Latino votes away from that ticket.
