Interestingly, Sen. Jim DeMint hasn't endorsed anyone in this race. DeMint heads the Senate Conservatives Fund — the PAC that has been the vehicle for DeMint to back ideologically conservative candidates over Republican ones in primary races. Given Pauls' political inclinations, this would be just the race for DeMint to take a stand. But Minority Leader Mitch McConnell has backed Grayson for some time, and Paul's chances were more uncertain when the primary race began. That may be more of a stand than DeMint is willing to take. As he told the Washington Post:
I want to avoid poking my finger in the leader's eye, but I'm not going to let it get unfair.
