Good for her. That's what a PAC is supposed to be used for. To pay for promoting a candidate. And WOW at 2 million just in a pac. That's pretty huge. Obvious she has a ton of support.
Actually no, it's NOT what a PAC is for, that's what a campaign committee is for. A PAC is meant to support/elect candidates based on the ideals of the PAC. Not to promote oneself. It's a very delicate legal line with about 3 bazillion loopholes in it that by all rights should be closed, but of course none of the elected officials want to close.
