I think Beto entering the race is a real threat to all, not just Biden. Beto had to be slightly cryptic running statewide in Texas. I hope he'll be more upfront running in the primary, and possibly in the general. I singled out Biden, because he will win with blue color everyday people. Beto poses a real threat to that coalition. Beto has more charisma, is younger, still a white male (fwiw), doesn't have the baggage. This isn't about beating Trump or ideas yet, this is about capturing the base, and I think Beto has the best shot at that.
