It is natural, in a balance of powers scheme, for each cog to assert itself over the others. In fact, that is exactly what judicial activism is. Courts acting against the legislature, or the Constitution. The Constitution provides remedies for these abuses, one of them being the public vote of representatives and executive.
Lord knows there are plenty of complaints from the executive, and if you ask me, that's as it should be. You can show me no court ruling or any documentation to support your side of the argument. And in the face of 200 years of the Senate exerting itself on the process to the full extent allowed, by all the strange means they employ, you simply protest. Of course you do, your "team", the guy you root for, is the president. Like many presidents before him--even George Washington--he is harassed by 100 Senators who refuse to bow to him. And again, that's as it should be. All you so-called republicans (or are you merely Republicans) who advocate lickng the president's boots ought to be ashamed of yourselves. George W. Bush, a medicrity, presumes more than did George Washington, an absolute human collossus.
And I say all that even though I don't want Schumer and Leahy to prevail. But, just like a team that gets whooped on the field, I have to hand it to them. They do a great job of playing defense. Actually, I think our system makes it easier to play defense than it is to play offense. It's easier to defeat stuff. Again, as it should be. I would like to see our side fight and win some good appointments. But then, to tell you the truth, even the great ones let you down. And we survive the bad ones.
