WELL, THEY ARE THE 40% PARTY:

Overhaul Splits Party Faithful (PETER WALLSTEN And JEAN SPENCER, 3/18/10, WSJ)

The survey found that opinions have solidified around the health-care legislation, with 48% calling it a "bad idea" and 36% viewing it as a "good idea" when presented with a choice between those two. That gap is consistent with surveys dating to the fall.

At the same time, Democratic voters strongly favor the legislation being pushed by President Barack Obama, particularly constituencies such as blacks, Latinos and self-described liberals. Those groups mobilized in 2008 to help elect Mr. Obama, but are far less enthusiastic than core Republicans about voting in this year's midterm elections.

The survey found a 21-point enthusiasm gap between the parties, with 67% of Republicans saying they are very interested in the November elections, compared with 46% of Democrats.
