Re: 100 days later
The 70% is probably temporary; once Obama loses control of the loons in his own party, it will probably go down. As for the Republicans dieing out- this is not the first time they went thru a hardship like this- Watergate and the first years of the Clinton Administration hurt them quite a bit but then Republicans bounced back big.
So as a Republican, I don't worry too much; the Loon Dems: the far-left ones, will screw up bad and the Republicans will take advantage of it. Its funny though that Congress's approval rating is still in the low 30s even with 2 years of power.
