Will Rubio's trash talk hurt Cruz?

Iowa Republican Sen. Charles Grassley voted for the USA Freedom Act. Rubio’s ISIS-would-support-that-bill accusation surely can’t sit well with the senior GOP senator in the nation’s first-voting state. (The other Iowa Republican in the Senate, Joni Ernst, voted against the bill.)

Iowa’s three-member Republican House delegation split on the bill, with Rep. David Young voting for it, and Reps. Steve King (a Cruz endorser) and Rod Blum against it.

In New Hampshire, the only Republican senator, Kelly Ayotte, voted for the USA Freedom Act. She most likely does not feel that she did the bidding of imagined ISIS lobbyists. (New Hampshire’s only Republican congressman, Frank Guinta, voted against the bill.)
