The Kobach win is a positive sign of Trump’s popularity. Kansans are notorious for voting for the incumbent, which Kobach isn’t. But also, the ‘moderate republican’ usually wins out here. Kobach ran as anything but moderate, running TV ads touting his support of Trump and his immigration goals. Seeing Kobach win here indicates that Trump still has very strong support, even where ‘moderates’ often win out.
Kobach was best known as Kansas AG for his fight against election fraud and cheating!
