Decades of racist attacks on voting rights have given the far right a virtual stranglehold on American politics. (And this doesn’t mean the neoliberal left is blameless.)
Republicans control Congress, the Presidency, the majority of state legislatures, and the majority of state legislatures. You combine that with the fact that most Democrats only defend their corporate sugar daddies and the result is a heavily right-wing agenda sweeping America. Many are now looking to the mid-term elections in 2018 as an opportunity to turn things around.
Efforts such as Bernie Sanders’ “Unity Tour” are meant to lure voters back into the Democratic fold and also to the polls. They also hope to encourage new candidates to run for office. Unfortunately, they’re likely to fall far short of their goal, thanks to voter ID laws, gerrymandering of districts, and a system called Interstate Crosscheck, all blatantly racist moves by the GOP which purged millions of mostly minority voters from the rolls or otherwise kept them home on election day.
