He backed Sanford's pro-Trump challenger, state legislator Katie Arrington, for November's congressional elections.
But Arrington has hammered Sanford for his criticism of President Donald Trump, and she enough GOP voters in the district may agree with her.
In the most recent count I've seen, Arrington is at 50.5 percent, only about 300 votes clear of a run-off (if my math is correct).
Caleb Frostman, the Democrat running in Wisconsin State Senate District 1, claimed victory in Tuesday's special election and Frostman's campaign manager, Hannah Akbik, told CNN that Republican Andre Jacque conceded the race in a phone call with the Democrat. Nevada, North Dakota, Maine and Virginia also chose candidates for the midterm election on November 6, when Democrats hope to capture a majority of the U.S. Congress. The onetime insurgent has made allegiance to his leadership a litmus test in many Republican races.
Republican Party unity: Trump's tweet about Sanford did not sit well with a number of Republican lawmakers in Washington, some of whom started a fight with the president publicly over it. But during the campaign, he ran ads saying how often he voted with the president.
The Argentina thing is a reference to the affair Sanford carried out while governor in 2009, when he went missing for about a week and was discovered to be spending time in Argentina with a woman who wasn't his wife.
He also slammed Sanford as being 'better off in Argentina'. She has sought to brand Sanford, who labeled Trump's tariff policies as "an experiment with stupidity", as a NeverTrumper.
Sanford has been an outspoken critic of Trump. "And unlike you, Mark has shown humility in his role and a desire to be a better man than he was the day before".
This news site has written numerous articles over the years chronicling Sanford's unfortunate evolution into a shill for the #NeverTrump "Republican" establishment. Luria, a Navy veteran and businesswoman, was her party's pick in the contest for the seat held by Republican Representative Scott Taylor, who's a former Navy SEAL. He is the second House Republican to lose a primary this election cycle.
That includes one of the most competitive districts in the nation, Rep. Barbara Comstock's in the outer D.C. suburbs.
Tuesday afternoon, the President endorsed her bid for Congress in a Tweet criticizing Sanford.
In North Dakota, GOP Rep. Kevin Cramer is a shoo-in to face moderate Democratic Sen.
It is fitting, perhaps, that the Republican Party's turn towards Trump's economic nationalism has coincided with Johnson departing the party to become a Libertarian and Sanford being tossed from its ranks.
In Nevada, Democrats are set to nominate Rep. Jacky Rosen to take on Republican Sen.
Republican Rep. Barbara Comstock in northern Virginia's 10th District will face the victor of a six-way Democratic primary. She needed to win a majority of the vote to avoid a run-off. Maine Governor Paul LePage is reportedly considering not certifying the results.
