From Barone's blog:

These Democrats have, at best, lost the capacity to distinguish between opponents of the president who wish the best for America and opponents of the president who don't.

Yes, E. J., "we have arrived at a dangerous time." And, no, I wouldn't use and haven't used the word "traitor" or the word "unpatriotic" in this connection. But it is these Democrats, not George W. Bush or their Republican critics, who have raised the question of whether they are on America's side.
