Bush can't get a vote on his high-profile conservative judicial nominees because the Republicans only have a one-vote majority in the U.S. Senate, and it takes 60 votes to break a filibuster. Nor do Republicans have an adequate margin to "go nuclear", i.e., force through a parliamentary ruling that says that judicial confirmation votes can't be filibustered.
There's a good chance the situation will change after 2004, since Republicans are favored to make net gains of at least two or three Senate seats and possible much more (depending on whether Bush wins in a landslide and has long coat-tails). If Republicans pick up enough seats in the Senate, Bush will be able to push through most if not all of his judicial nominations. He'll be able to fill Supreme Court openings with more principled Justices, and his track record so far on lower-court nominations suggests that he will do so. Several USSC Justices, from all portions of the political spectrum, have just been hanging on and can be expected to resign before 2008.
So from an RKBA perspective, the makeup of the Supreme Court is likely to improve (perhaps dramatically improve) over the next 4 or 5 years. It's better to wait for that ideological shift than rush a bad case to them now and get a bad decision.
In the meantime, the Congress is unlikely to pass significant new gun-control legislation. Both houses are controlled by Republicans, so legislation can be bottled up in committees. And even many Democrats are not anxious to get into a scrap over gun control, convinced as they are that it cost them the Presidency in 2000 and other races since then.
Gee... don't do me any favors.
As for the illegal filibuster on an equally illegal 60 vote "majority" passed by Little Tommy, why not just change the rules back to what they were; simple majority. Hell, the Dims only passed that onerous turd of a rule because they KNEW it'd give a slim Conservative majority conniptions.
I do not trust an undereducated, stupid, easily biased public filled to the brim by the likes of Peter Lemmings, Catie Colon, and Dan Blather with their leftist Hate to hand the R's back a win next election. Not the across the board sweep that your scenario requires.
My Rights, they are your Rights to remember, should NEVER be held hostage like this.
