Not so.
I remember this talk in 1992. Lots of pundits writing articles calling and predicting the demise of the Repubs.
F*cked up? Absolutely. In many ways.
But dying, no. The Governor and Congress, and Senate attest to the fact that the GOP is a full force in the game.
And of course - the US is only a 2 party system. There is no alternative.
The GOP is odd IMO, but weak? No. Dying? Not even close.
I think people are focusing too much on the potus elections.
