I agree such a high majority has a lot of potential dangers.
On the other hand, no one was talking about how scary a Republican majority in the three branches was in the 2004 election... or at least not to my memory.
Would all of you honestly been happier if McCain had won?
I would be happier if we had a bipartisan government. McCain as president, or at least a sizeable enough portion of Republicans in one half of the Legislature to block bills. Last I checked, Republicans hold 40 seats in the Senate to the Democrat's 54--and I don't know about the status of the remaining 6 seats. In the House, the Democrats control 60% of the seats (upon last check). Both ways, they can push most legislation through without ever listening to Republican opinion, especially as not every Democrat has the same agenda, and not every Republican is a cookie-cutter version of dear old W.
Anyways--the advantage I see for a Republican majority in government is that Republicans, on a whole, don't push as much controversial legislation. We really can't take W.'s agenda as a view of a conservative, true Republican agenda. What I mean is I feel that liberal judges allow typically for more flexibility, and on the Supreme Court, their check on other branches of government is to declare legislation unconstitutional, and forcing an amendment if the law determined unconstitutional is to be reenacted. I would rather they strike down more legislation than less legislation, though I do realize it doesn't always hold true.
Anyways--do realize that only 2-3 of our Justices were seated under Democratic leadership: of the nine, most are in office because of Reagan, H.W., or W..
