David Frum has been hit-or-miss recently, but this is exactly right.
The problem with the Republican leaders is that they’re cowards, not that they’re fundamentally mistaken. The real locus of the problem is the Republican activist base and the Republican donor base. They went apocalyptic over the past four years, and that was exploited by a lot of people in the conservative world. I won’t soon forget the lupine smile that played over the head of one major conservative institution when he told me that our donors think the apocalypse has arrived, that Republicans have been fleeced and exploited and lied to by a conservative entertainment complex.
I would rather the Republicans continue down this slow-motion trainwreck path. However, if they're smart, they'd listen carefully to Frum. Too bad they're not very smart.
