Sure Trump could do something to lose my support, but that’s unlikely.
The larger question is: Can Democrats do anything that would gain my support?
Not without fundamentally changing all their policies and becoming an American party again.
(Is there anything Trump could do to lose your support?)
I would vote for Donald Trump even should his body be laying in State beneath the Rotunda. (However incorrectly I may have phrased this, I imagine you can get my drift.)
