Rove is no dummy, but I disagree with him. I think Trump would draw and quarter Biden, and he would not need to work up a sweat doing it. And the Dems know it too. Joe Biden is no match for Trump. And with Biden uttering his idiocy to move further left, Trump would have a field day.
Biden has already gone on record to shut down the fossil fuel industry and imprison executives. I remember Clinton saying something similar. It cost her WV and PA, and perhaps OH because they are another state big in fracking. Biden didn't learn anything from her mistakes. I love it! He supports the Green New Deal too, and I think Trump buries him over it.
The ONLY person that would have a chance against Trump is Clinton. If there is a brokered convention, I see her emerging and not Biden.
