Not going to happen.
Trump will have more than enough delegates to win on the first ballot.
If it was a contested convention, all bets would have been off.
The GOP is not going to commit political suicide by dumping someone who won the nomination fair and square.
And rank and file Republicans are closing ranks behind Trump.
They had better keep closing the ranks and accept the best they’ve had in years to win an election. TRUMP!
They had better honor Trump’s choice for Vice President.
They had better not pass rules for 2020 to turn it into an insider grab with more hocus pocus caucuses.
