My G, two things have happened that solidified the race IMO. 1) AOC, Tlaib and Omar endorsing Bernie has energized the base and the youth 2) with Bloomberg entering the race I think it is official, the wealthy are scared shytless and are flailing for last ditch efforts. The populist movement is inevitable. Bernie will either power through or be cheated so blatantly it will end the Centrists as trust worthy actors for good. Leaving Progressives to take over. If Bernie and progressives continue applying pressure @ the current clip they can't be stopped. Just my assessment, I could be wrong.
Thats how I feel. The more Centrists come in the race, the more it takes away from Biden. For Bloomberg to join in so late, means that he is scared that his precious wealth will go through the hands of poor people and exposes his hatred for progressive policies.
