It's no big secret that liberals have long been at peace with science & evolution's part in that, by contrast to conservatives. It just proves that liberals aren't 100% wrong, even if they're close....
Yes, its no big secret that the liberals use Darwinism as a world view as opposed to conservatives like, the President (it is no secret where his 'world view' comes from and the liberals hate it )
That doesn't necessarily mean they're scientifically literate though; in many cases it's simply applying the rhetoric of science to politics (just like the IDers do to religion), and they only "support" science to the extent that they see it as a bulwark against their enemies. If Muslims started to demand equal time for Allah in biology class, or some feminist Wiccan demanded that they teach the Gaia myth in her children's classroom, don't be surprised if they'd make an about face
