Trump didn't so much choose Gorsuch as turn the process over to a cabal of extreme right wing one-percenters as a thank-you for their support. His appointment will darken the lights at the Supreme Court for decades to come. 

As backward and narrow Gorsuch's constitutional mindset might be, Republicans would - in ordinary circumstances - be entitled to appease their conservative base. But these are not ordinary circumstances. For a full year, Republicans refused Obama's much more qualified nominee Merrick Garland even the courtesy of a meeting let alone a hearing or an up and down vote. 

Democrats won't succeed in blocking Gorsuch: the GOP will invoke the nuclear option to get him confirmed. But a filibuster would send a clear message that Democrats are no longer a party of wusses - that, like the GOP, they are willing to go to the mats for their beliefs. 

If they give Gorsuch a free pass, they might as well kiss their chances in the 2018 mid-terms good-bye.
