I have to chuckle about that now. Sure the libs succeeded at the time at making republicans radioactive, but even then, in the '76 presidential election, Carter only managed to barely win over the bumbling Ford, only to be plagued by a TRULY crumbling presidency, opening the doors for Reagan to swoop in. Even a few liberals I know wish Ford had won instead of Carter, believing it would have prevented a Reagan Revolution. The dems should be careful what THEY wish for, yes history could repeat itself again--only not in the way they hoped.
The country almost went to hell with Carter. Bringing in Reagan made that catastrophe worth it. Is the rise of any current or future Republican worth a Hillary admin with congressional majorities? Remember in '74 the lefties in the Dems were the low level congressmen. the party was still run by adults. Those lefties are the party today and the younger Dems are even more leftwing. Today I don't think any future outcome is worth a repeat of '74.
