Republicans took the House for the first time in 40 years in 94, remember? Worked with Clinton, got some stuff done which Clinton takes credit for. Dems have had control of the Senate for most, if not all, of the last 80 years along with the House. Republicans can't grow balls until the voting public does.
The current Tea Party members in the House and Senate are a classic study of what happens to those who do stand for the core principals of small government, minimum regulation and market based capitalism. It gets labeled as too "extreme" by the left and moderate right. O' Reilly is a good example of what I mean with his dismissive attitude towards the Tea Party.
