“If you look at a race in a state like Missouri or North Dakota — or any of these states — he’ll be very involved,” said Sen. Cory Gardner of Colorado, chairman of the GOP’s campaign arm, who speaks with Trump about political strategy regularly. “He’ll be actively campaigning for a Senate majority. Absolutely.”

Republicans will lean most heavily on Trump in five deeply conservative states where the president remains highly popular and where he crushed Hillary Clinton: West Virginia, North Dakota, Indiana, Missouri and Montana. But they say they will also deploy Trump in the next tier of swing states that Trump won more narrowly: Ohio, Pennsylvania, Michigan, Wisconsin and Florida. And they expect him to help preserve GOP seats in Nevada, where he narrowly lost, and in Arizona.

In fact, despite his unpopularity on the national level, Republicans insist there isn’t a state on the Senate map where they are nervous about deploying Trump. Republicans reason that opposition to Trump is already baked into the Democratic electorate. They figure Democrats will be motivated to vote whether Trump shows up or not, so they might as well use him to fire up their base, too.
