Marching and chanting have lost the power to move the needle. There are exceptions of course, but I contend that protest has an ever diminishing power to move us. With a few caveats (border policy on children for example) It’s hard to point to any policy changes that are a direct result of a protest movement in the last 5 years, in spite of record setting rallies and marches.
This movie will end like the Gorsuch show did, the outcome having been scripted with the 2016 election results. The Democrats do not have the votes, and barring something very unforeseen there will be a vote on Judge Kavanaugh sometime in the next 30 days or so.
