I appreciate your points.
Personally, I cant tell you or myself what I will do on election day.
Both 2008 and 2012 were tough ones, I liked neither GOP candidates and I don't like Trump now.
Both were last minute tough decisions.
But its pretty darn petty in my view to threaten to help elect Hillary if the nomination doesn't go our(any one of us) way.
I sure wont be threatening to help Hillary if Trump wins it. That would be childish,
“...I sure wont be threatening to help Hillary...”
Under ANY circumstances.
