Bob, I don't think the purpose of the Arroyo interview was to GAIN him votes, but to stop the bleeding. There are a lot of older very/extremely conservative religious and political Catholics who are disgusted with Trump, especially after the Access Hollywood tape, and the Al Smith Dinner fiasco certainly didn't help.

So his campaign has to carve out precious time to reassure voters who should have been his to begin with. Not a good thing for his campaign, and it shows you what bad shape he is in.
