Why I like the filibuster
One of the things that's brought up to justify trying to kill the filibuster is that there were some pretty monumental filibusters in the past by the anti civil liberties trolls who used to infest the Democratic Party (and who have now moved en masse over to the Evil Party), so that means there's something! wrong! with! the! whole! idea! This argument is usually followed by a childish "and Democrats are poopyheads!", which tends to diminish the gravity of the argument, but it's still an interesting one.
It's also wrong. The claimed undemocratic nature of a filibuster (that you need to get a supermajority to get over the barbed wire and on to a vote) has a lot of company in the United States. Got a bill vetoed by the President (when the United States still had a president, and not a gang of unelected fascistic thugs)? Why, you need a supermajority to override that veto and get the bill converted into law. Need to win the presidency of the United States? Once again, look, it's "undemocratic" in that you can win (or "win", in the case of the overthrow of the US government in 2000) the presidency without getting a majority of the votes (an undemocratic system that's reflected in the Senate of the United States; The Democratic Party represents more citizens than the Evil Party does, but, funnily enough, the Evil Party controls the Senate because they've managed to sucessfully bambooze and bribe a majority of the voters who live in the dinky little rural states that make up the vast majority of the United States.) The United States is *not* a democracy, and the Evil Party sycophants who are now pretending that it is are not doing themselves a favor by doing so.
But, even if we assumed that the United States was a democracy (that just happened to have the hideously undemocratic electoral college, and that just happened to have the hideously undemocratic arrangement of two senators per state [offer not valid for the District of Columbia and other territories]), I'd still like the filibuster because the tottering construct that is the US legal system (at least until Maximum Leader Genius sneaks a "I can abolish any law at will" paragraph into some appropriations bill) contains structures that were supermajoritied through, and which would become vulnerable to the anti civil liberties trolls who are now proudly bigoted members of the Evil Party.
2 or 3 blatantly unqualified judges won't make any difference in the long term -- impeachment is the solution to that little problem -- but being able to just make all those pesky civil liberties laws like, oh, interracial marriage, prohibitions against marital rape, child labor, and poll taxes just go away is the sort of thing that would make the heart of a bigot (assuming, of course, that he had one) beat a little harder. So, sorry, I don't see any reason why the Evil Party should have an easier job rolling back the enlightenment than the liberals had when they were putting the enlightenment into place.
