Trump ally Senator Lindsey Graham won the South Carolina primary vote on Tuesday, narrowly avoiding a runoff with right-wing challenger Mark Lynch, a South Carolina small business owner and Baptist deacon running an “America First” campaign. Graham barely held on to 50 percent of the vote in polling leading up to Tuesday, but cleared the vote with a 6.8 percentage point margin. This was still the closest Senator Graham has been to a runoff vote in his twenty-three years in the Senate.
Evidently, Lynch’s platform moved some Republican voters who might be frustrated with Graham’s hawkish tendencies or are simply bored with the D.C. establishment. But Lynch killed his credibility with a sufficient number of voters by descending into vitriolic, half-there accusations instead of operating with just one iota of decorum or rationality.
On June 9th, you have an opportunity to elect a true conservative.
An America First candidate who believes in God, the Constitution, secure borders, fiscal responsibility, and putting South Carolinians before the political establishment.
Don’t sit this one out.

Lynch’s criticisms against Graham could be strong, had he just delivered them as a normal human being. After all, the critiques have been delivered by other sources before. His largest opportunity was to target Graham’s political weakness: the incumbent’s staunchly interventionist stances on Ukraine and Iran.
A coherent criticism would center on how military intervention drains valuable American resources, or how such campaigns risk the lives of American military personnel abroad. Instead, his campaign material stated time and time again that “Lindsey is a childless warmonger trying to avoid being blackmailed for being a homo by sending Our Boys to every war he can dream of.”
Nice.
Lynch chose to play the whackjob and squandered the opportunity to force a serious debate about American intervention and Graham’s other unpopular stances by employing ad hominem, focusing on Graham’s alleged sexual proclivities instead of the actual issues at hand. It is frustrating to watch political figures repeatedly abandon substantive criticism in favor of rumors and personal attacks. Lynch is only another example of the decaying standards of behavior plaguing American politics.
At least South Carolina primary voters — however attracted they may have been to Lynch’s bellicose America First platform — value decorum and reasoned argument just as much.
