Trump hammers culture war attacks on Andrews in final rally for Graham
Three rallies in one state is a lot of presidential capital to spend on a Senate race, even in a reliably red place like South Carolina. That alone tells me Graham's team believes the race is closer than the state's recent voting history suggests, or at least that they don't want a complacent base. When a campaign reaches for culture war themes in the final days, it's usually aiming to energize its own voters rather than persuade anyone in the middle.
The "radical left" label is a familiar one, and without knowing the specifics of what Trump cited, it's hard to weigh how much of it lands. Annie Andrews is running as a Democrat in a state where that's an uphill climb, and her campaign has likely spent months trying to focus on local issues. Trump's closing argument pulls the race back to national terrain, which tends to favor Republicans in South Carolina.
I'd want to know which specific culture war issues were raised and how Andrews responded. The rallies may matter less for the outcome than for what they say about the national party's playbook in red-state races.
