Executive editor Fred Barnes discussed Tuesday’s tightest and most significant congressional primary races with the Wall Street Journal’s Mary Kissel.

Florida senator Marco Rubio “came back from losing the presidential race and then big-footed his way into the race.” He’s up against Carlos Berruff, but “he’s still very, very favorably regarded among Florida Republicans,” and Donald Trump’s dismal polling in the state is not affecting Rubio at all, Barnes said.
