There is a time for “answer a fool according to her folly, lest she be wise in her own eyes” (yes the bible uses the masculine form here, but if the woman insists the other-gender shoe fits, then she should be told to wear it).
Could an entire campaign be carried on at this level? No. But that is also not where Trump is. Kelly tried to frame Trump in with that question and she got blasted in response. Bring up some real issues and watch Trump shine.
I know he can shine brighter than everyone right now. That has me excited but whinling about a girl no.
