What happened in every key primary race last night

John Warren and Henry Mc Master head to runoff

Sanford is also not alone in facing backlash as a Republican willing to voice his criticism of President Trump.

Meanwhile, longtime state Rep. James Smith has won the Democratic seat.

As results came in Tuesday, Sanford told a crowd in suburban Charleston: "I've always been a realist and at this point, based on the numbers I see, I'm going to lose this race". But he failed to win the 50 percent necessary to avoid a runoff. The incumbent, a frequent critic of the president, lost to state legislator Katie Arrington, who vowed to be more supportive of Trump if elected to the House in November. With just hours to go before the polls closed when Trump sent the tweet, it's unlikely his message was the deciding factor - but it served as a notable warning for members of Congress who defy him.

That was not enough for Trump, who also mocked Sanford with a reference to a 2009 scandal when the then governor disappeared for days before surfacing to say he was "hiking the Appalachian Trail". In an ad released last month, Arrington mockingly alluded to Sanford's past infidelity and vowed to go to Washington to "get things done, not to go on CNN to bash President Trump". In a February 2017 Politico piece, he said Trump has "fanned the flames of intolerance". After attacking Sanford, the president backed Arrington. "I look forward to working together with him to drain the swamp and continue making America great again".

With 16 percent of the vote in for South Carolina's 1st District, both incumbent Mark Sanford and challenger Katie Arrington remain almost tied, with the AP giving both candidates 48 percent. The Cramer-Heitkamp matchup could potentially be a tight race, but in a state that Trump won by more than 30 percent in 2016, Heitkamp will likely lean on her moderate record and support for certain Trump policies.

McMaster, the former lieutenant governor, assumed the governorship past year after Nikki Haley resigned to become US ambassador to the United Nations.

Arrington will take on Joe Cunningham, a construction lawyer and yoga studio owner who won the Democratic nomination Tuesday. In Virginia, women won Democratic primaries in four out of four congressional districts that could be competitive this November.
