It's early and one poll doesn't mean much if anything. RCP has no averages and neither does 538. I have to question McConnell being up by that much.
Now there's a good chance of Biden winning Texas and also Georgia. Now that is as of today with still 100 days left prior to the election. The campaign season hasn't started yet.
It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
