Wow, all anti-Biden stuff from people who seem to like Bernie Sanders. Apparently some Bernie Sanders supporters seemed to have no problem with the Mini Super Tuesday election 7 days before the Arizona, Illinois, and Florida election on March 17, but they had a big problem with the March 17 Primary only 7 days later. So, what made them suddenly start acting like having further primaries was essentially an act of genocide against Americans, especially older Americans?
Well, it turns out from what I have been reading online that some of Sanders supporters want to delay any further primaries a lot in the hopes that some magical surge of support will come out for Bernie Sanders. Where will this magical surge come from? I have no idea. Perhaps they think that Bernie Sanders fighting against the Coronavirus will rally people around him, so they just need time for Bernie to work his magic. So, expect a whole lot of "having primaries now equals death" from some anti-Biden and pro Bernie Sanders supporters.
