They are hoping that some scandal will force Trump to drop out, which might result in them getting at least SOME delegates, which they can use as a bargaining chip for favors at the convention.
The problem is that Trump is immune to most scandals.
I live for that day when Trump is sworn in while Obama has to watch as the presidency is transferred to Trump. The look on Obama’s face and Michelle’s is what I live for.
It will be delicious.
