While its good that parties are free to elect their people the way they want to, it is in some ways funny to say that "democracy wins" in respect to caucuses. They are extremely undemocratic as they allow for voter intimidation, and they disenfranchise voters who can't make it at the specific time.
It doesn't seem right to change the rules at the last minute, but caucuses should be done away with alltogether, they are a horrible way to select a nominee. I can't imagine why anyone would support them, other then of course Pabster here who I'm sure would be vehemently arguing against them if Hillary wanted them.
