President Trump may not be running for reelection yet himself, but the days and weeks before the 2018 midterms have been busy for him nonetheless.

Greg Gianforte running for re-election; on Friday he went to Mesa, Ariz., for Senate candidate Martha McSally; and on Monday he’ll be in Houston for Sen.
