Just thoughts............
Age aside, I don't think the founding fathers of this country ever anticipated or considered the idea of career politicians. Term limiting the House and Senate I think had the idea that the "house" (both chambers) would be cleaned from time to time and I think they would be horrified to see the mess things are in now and would be very critical if not outright condemn the career politican idea - doesn't work very well for a Republic which is what they founded.
Being here in Tennessee my two Senators and my Representataive are Republican and, generally speaking, do OK for me as I tend to come down a bit more on the conservative side of things however, that being said, I've had some issues with one of them and their voting/support of some things and I wrote him and told him I had no problem seeing him gone if he wasn't going to, again generally speaking, listen to the people here in the state and I would have no problem voting against him and the same can be said for my Rep on the House side - indeed just about all of them have been there too long as it is. I do have to tip the hat to my Rep for having the b@lls to vote against the terror war - one of very, very few republicans who did..... he didn't see that as the answer and thought it was far, far to expensive to do so and has been very vocal about it locally and has stood his gound against the critics yet has not has any problems with getting re-elected and that, I think, is because people respect him - he will make the hard decisions when it's not the popular thing to do.
Yes, we need to clean house on both sides of the aisle and if that happens one has to wonder how Mr.Obama would handle things then especially if he ended up loosing his majorities in both the Senate and House or if a bunch of newbies were put in that kept his majority but didn't necessarily go along with things like the current crop does. Interesting what might happen this fall...... we shall see.
Back to the orginal part of this response - no, I don't think that things as they are now in government, especially the federal part, are anything like what the founders had in mind.
