The Senate is not supposed to hand pick its own membership. Or block from election (through the NRSC) those it doesn’t want. But that’s exactly what’s been going on.
And it’s how we end up with so many pantywaists.
It's also how we wound up with a Democrat as governor of Louisiana and so few Republican congressmen from California. Acrimonious jungle primaries help nobody but the Democrats.
They don’t want anyone who would side with the citizens, the rule of law or the Constitution.
