He won't ever touch this again IMO, will just be a big L for him. Someone probably showed him some statistics of how a majority of people who vote for him wouldn't be approved for CC's and have to go to payday loan shops etc for cash.

I wonder if the alt-right has picked up on this gap in the marThiel?
