My statement about "myopia" was that you implied that there was a long list of candidates who might win the nomination, and I think that even in the Republican Party of 2006 most of them would end up losing.

The GOP in PRESIDENTIAL elections ends up picking the more moderate candidates, but the loud ideologues manage to get elected in their districts, then run for President and drag the debate so far right that no moderate candidate can win a general election because he's had to tack so far right in the primaries that he has lost all credibility. Christie would make a good candidate, but if he enters a primary with the shrill likes of Bachmann impugning his credentials, even though she ends up getting "kicked to the curb", as you put it, the damage is done because he has to show how conservative he can be.

The Democrats, somehow, have candidates that can be centrist without upsetting things. That's why I'd like to see Warren involved in the primaries - so they can finally understand what it feels like to have to moderate an extreme primary message in the general election, only to lose because of it.
