I do think we need to coalesce around Republicans. Not slavishly or absolutely, but as a general rule.
This was the path followed by Ronald Reagan and it eventually led to him winning the Presidency.
Changing the GOP to a party MORE IN TUNE with the Constitution is a Herculean task to be sure. But not impossible...and worth the effort.
They also refused to abolish the DOE, one of Reagan's campaign promises. The DOE has contributed mightily to the destruction of the Republic.
