I really hope Democrats make gun control a foundation of their mid-term election platform. If anything will get Trump voters back out to the polls, that will.
As for Republicans, they have been squishy on ALL issues, not just gun issues. I can't believe they actually passed the tax cut in December. I don't think the R's will lose out in the mid-terms, but I still expect Democrats and the press to do all they can to make that happen.
