Trump tends to treat Congress Critters like they are employees of the voters who elected them. How ironic is that? What the filibuster does is give sleezy Senators, like John Kerry, the ability to say  "I voted before it, before I voted against it."  

The only way to get rid of the filibuster is for the voters to put the pressure on the Senate.  the filibuster, in the hands on honest men, is a good thing.  However, there are few honest men in Washington D.C. these days.
