Worse, because the total number of Republicans he causes to leave the party plus new voters who register to vote against him is greater than the total number of new voters who register to vote for him.
That's not true and you know it. First, the NeverTrump movement is all but dead. The former members of the said movement will eventually all join Trump, save for possibly a small number of holdouts.
The reason for this is simple: If Hillary is allowed to rein supreme and completely unchecked, akin to a medieval Queen, or a Russian Empress, the United States will quickly become Hell on Earth. The Republicans know this and Trump will keep reminding them of this simple fact for the next five and a half months till Election Day.
Vosem, just think of what kind of havoc Hillary will wreak on the Constitution and our way of life if she is allowed to name three or four justices.
