What if they were to harp against "Southern backward racism" and whatnot and effectively did they were not welcome in the party? Would voters be more likely to switch sides or form a new party? What would the electoral consequences be, and how long would the GOP need to recover?
They won't do it.
The Republicans' percentage of the U.S. Popular Vote, in recent presidential elections, has accounted for around 90 percent from white voters.
From their base states among the Old Confederacy … they're at a rate of over 100 percent from white voters.
More than 100% of their voters in the South are white? How is that possible? Do white Southern voters vote multiple times?
Not exactly what I was saying.
I'm addressing the Republican Party's dependency on the vote from whites nationwide and numerous states.
But, I'm going to correct myself (after having gone over the numbers).…
