I think they realized that the state telling them to pound sand (which was looking more and more likely) could hurt the federal case.
I think they also realized a lot of their people were voting this way in the outstate areas.
It is interesting...my gut tells me they are seeing that Minnesota is not happening (even Trafalgar has Biden +3 and they suck) and so they pull the petition. They still might have a fight for other races in state though (maybe Tina Smith) so you don't fully drop it you just wait and see.
I dunno I gotta believe someone inside the campaign told them wasting time and resources on a state you have little chance to win is not good when you have a bunch of states you need to defend that are in trouble.
