We desperately want blue, but purple will do (for now):
Running in a key presidential battleground, Tillis has to hope things go Trump's way here. The first-term incumbent, who only narrowly won in 2014, ended up avoiding a contentious primary but had to spend money and political capital in the off-year to do it. He didn't make many friends with an infamous flip-flop on Trump's border wall, first penning a Washington Post op-ed against use of an emergency declaration to secure funds for the wall and later, in an appeal to Trump, reversing his position.
He's up against former state Sen. Cal Cunningham, a member of the Army Reserves. It'll be an expensive race, with forces on both sides of the aisle already having booked millions of dollars for TV advertising. Cunningham is outpacing the incumbent on fundraising, bringing in $7.4 million to Tillis' $2.6 million in the second quarter.
