Like what? Only thing they do is pass is tax cuts for the rich and leave it at that. Literally the only major partisan bill that the 115th congress produced was the "Tax Cuts and Jobs Act of 2017". They came close to doing a "skinny repeal" of ACA by budget reconciliation until McCain got confronted by the Grim Reaper in the bathroom and voted no.

Abortion, Immigration, Same-sex marriage, gun rights, etc are all just convenient boogeymen that will never be tackled by them because what do you use to scare your cousin-fucking base into the voting booths if you "fixed" all the issues? Filibuster's just a convenient smokescreen because "Ah schucks, sorry guys, we can't override state requirements regarding carry permits because democrats won't play ball".
