The only thing the "GOP" can do is totally disavow Trump, kick him to the curb and completely reject everything he and his idiot followers stood for.
The GOP is for free trade, is not racist toward minorities, does not hate Muslims, has no animus toward women nor treat them like dirt, is completely opposed to spending huge sums of money on infrastructure, favors reform of Medicare and Social Security, and doesn't hurl insults at the handicapped and at each other.
Trump must be put in the rear-view mirror and never acknowledged in the party again.
