Biden won’t do better than Beto, who got more votes than Hillary Clinton in a midterm environment. There won’t be a groundswell because there’s no more room for Dems to grow in states like TX, GA and AZ compared to 2016.
Texas has some of the lowest turnout in the entire country (literally in the bottom five consistently), not to mention being one of the fastest growing states in the country at the same time.
How do you possibly fathom Democrats "have no more room to grow" from 2016? That makes absolutely no sense whatsoever.
