Really? Why did Ben Carson get so many primary votes? Why did Marco Rubio get so many primary votes? Why did Ted Cruz get so many primary votes (including mine)? Why did Alan Keyes get so many primary votes (including mine, twice)? Remind me ...... who drove Herman Cain out of the 2012 R primaries?
Again, it doesn't matter what Republicans did or didn't do. Unless they support the "progressive" agenda, i.e. massive amounts of taxpayer cash spent on worthless liberal feel-good programs, they will be labeled as racists.
If any current white Dem pols do not support the "progressive" agenda, they will be called racists as well.
Slick Willy was outraged at being called a racist by some black pols and talking heads when Hillary ran for president in 2008 running against Obama.
What was Hillary's sin? She was running against a black pol, ergo, she was a racist.
Her agenda was virtually the same as Obama's, but when going head to head in some primaries Obama got about 90% of the black vote.
So it really wouldn't matter if Trump and Pence resigned, and the next two Republican president and vice-president candidates were black. If Republican pols don't support the "progressive" agenda, they will be called racists.
