Victor Davis Hanson: "We had a senator named Joe McCarthy that did, and we know how that ended up.But Joe Biden is all for unity when his polls are above 50% and when he's desperate.
And so far his polls are dropping even this week as I speak, down back to 38 in the latest Reuters.
Then he tries to divide the nation and we know how that's going to end up.
It's not going to end up well for him.
But it's so predictable.
