Did Palin make an endorsement in that race?
Palin gave money to Rand Paul but I don’t remember her campaigning for him and she always said giving money was not an endorsement. This is Rand Paul’s moment and no one else’s as he ran a really good campaign.
IIRC Sarah was the first out of the box to endorse Rand-—and it made a huge media splash. My KY relatives tell me her endorsement helped drive Johnson out of the race and focused national media attention on the election there.
