I very much agree with those that point out that the first six years of GWB has given us a very distorted view of "normal" US governmental operation. But the GOP, during the first six years of GWB was lock step united behind the Presidency, and the GOP held the House majority and Senate majority except for a few years.
The only comparable period might be during the the first few years of LBJ, where legislation was cranked out with more regard to quantity than quality.
A more serious student of US history can point out many examples where the legislative branch has completely frustrated the agenda of the then President. And we need only go back to the GHB administration to see a classic case. Because after the profligate spending of the Reagan years, the legislative branch completely ended any GHB domestic agenda, and somewhat as a result, GHB spent his time conducting foreign policy, an area where the President has more constitutional freedom of action.
The anti thesis of that is the last post WW1 years of the Wilson administration, where the legislative branch effectively killed the Wilson vision of the League of Nations.
And any serious student of the US Constitution can point out that the US President has little real power, and the power to make laws is really vested in the Legislative branch. And what has somewhat increased US Presidential power has been the tendency to vest more and more of the information gathering power in the executive wing. And with countless agencies added post WW2, almost all the growth of the US government is under the executive branch. Not only have we seen a huge growth in tradition cabinet positions named in the constitution, we now have huge countless new agencies like the EPA, health and human services, and now we have added Homeland Security. Even a year into the Obama administration, Obama has barely seized the reins of power in these agencies, and unlike GWB, Obama is not using them as bludgeons.
Sadly it has somewhat become the policy of the GOP to lock step resist everything in the Obama administration agenda. And credit where credit is due, the GOP is very good at maintaining unity, although we have to wonder if the GOP has any real agenda to govern on. The real question is in the future, will the American people reward the GOP in the election of 11/2010 for resisting "CHANGE" or not. If the GOP gets punished for the third election cycle in a row, it will effectively end the GOP tyranny of the minority that now rules the day.
