Trump represents a very old disease in this country.  The answer is education, although there are certainly young cops that are still part of the same problem.  Of course, the older cohort is not being replaced as fast as it is dying out, so this may be its last stand.

Republicans being loyal to their congressman may or may not be a problem, since these districts are gerrymandered anyway.  The question is whether members of the House Freedom Caucus are coming back.  The smaller that group is, the better.

Any ad dissing Trump is a good thing. I doubt there is a downside.  Anyone who would be taken aback by Khan's religion and ethnicity was not voting for Hillary anyway.
