It's a defunct party. There's a crisis of leadership. It's mostly because nobody know what it means to be a Republican anymore.
It will probably be 12 years before we ever see a Republican president, and I would be surprised if 10 of those years aren't with House and Senate democrat majorities. And that's without mentioning the Supreme Court. The next century will be a leftist century. Just like the last one, I suppose.
Ehyeh asher ehyeh.
"You and I are told we must choose between a left or right, but I suggest there is no such thing as a left or right. There is only an up or down. Up to man's age-old dream – the maximum of individual freedom consistent with order – or down to the ant heap of totalitarianism." -Ronald Reagan
