I think Siddharta nailed it when he said, " The GOP are working to make their ideological turf smaller, obviously they do not care about popularity."
But when the popular vote is a measure of democracy, and who is elected and who will not be elected in the next election, caring about popularity is everything for a political party.
The only way the current nihilistic GOP strategy can work is to bet everything on the democrats failing.
But the most comparable period to the present was in the aftermath of the Great depression of 1929, where Hoover was the unlucky smuck who got to inherit eight years of short sighted GOP policies that finally reached critical mass. And even if the democrats under FDR failed to fix it, the voting public seemingly remembered who broke it, and the GOP did not benefit at the polls. Nor did the GOP see the Presidency again for two full decades and a democratic majority persisted in the house, unbroken, for a full 62 years.
Therefore, the GOP is playing a very dangerous game, and stares at extinction, straight in the face.
Worse yet, lost to retirement are many fine GOP moderates like Chafee, Warner, Hagel, DeMedici, and about all the Republicans have left for a role model is help rebuild is Lugar and what I regard as a conservative in McCain. Of course there is still Snowe, all GOP politicians that could contribute to government, from the majority or the minority.
And since Powell still has a lot of bi-partisan support, the GOP would be fools to not learn from Colin Powell.
