The interesting thing is, they are immediately making the same mistakes the Democrats made before them, the Republicans before them and so on.
In 2004, riding on Bush's momentum, Republicans picked up a couple of seats in the House and Senate. This was considered a major victory. The Republicans acted as though this would last forever. It did not, coming to a crashing halt.
During the '06 and '08 elections, the Dems picked up several seats in both the House and Senate, as well as the President. This was considered a major victory. The Democrats acted as though this would last forever. It did not, coming to a crashing halt.
Now, the Republicans have picked up the House majority as well as gained a couple of seats in the Senate - and have once again considered this a major victory that will last forever. It will not. Like all recent political movements, the Tea Party will come to a crashing halt, and is in fact doing this as we watch.
I've a feeling that the union-busting/anti-government worker movement will come to bite the Tea Party in the ass, in the end. Voters' memories are not that short - after all, the next elections are only 20 months away (no...seriously). The Tea Party has dug itself quite the hole with the general public - one so deep and steep, I doubt it has the ability to reverse that trend in that short of time, however, a great ability to make that hole much deeper and steeper.
Then, the trend will continue, on and on and on and on and on.
