Senator Sanders didn't do this of course because HE understood the importance of electing Sect. Clinton, an importance that is now thrown in our faces day after day. Had enough progressives been able to grasp the importance of "vote blue no matter who" there would BE no challenge to Roe v. Wade, the Texas abortion ban would have been tossed out by a 6/3 progressive Supreme Court within days of its enactment. With this court in place the protections of the Voting Rights Act would have been restored and there would be little need to pass new voting protections, and there's little doubt that challenges to the new red state laws restricting voting rights would succeed. Challenges to partisan gerrymandering would have found friendly ears throughout the federal judiciary, challenges to president Obama's clear air climate rules (EPA regulation of C02 as a pollutant) would have failed...the trump admin did far too much damage to progressive causes to list here but I hope you get the drift.
