Though I can't find the link right now, the post-2000 typology had liberal democrats at about 11-12% of registered voters.
there's been some realignment (the 2000 name is the first one listed)
http://people-press.org/reports/display.php3?PageID=949there's also a questionnaire just in case you were wondering if you're a closet "social conservative"! hahahaha
here's a piece from the summary:
The Left
At the other end of the political spectrum, Liberals have swelled to become the largest voting bloc in the typology. Liberals are opponents of an assertive foreign policy, strong supporters of environmental protection, and solid backers of government assistance to the poor.
This affluent, well-educated, highly secular group is consistently liberal on social issues, ranging from freedom of expression to abortion. In contrast, Conservative Democrats are quite religious, socially conservative and take more moderate positions on several key foreign policy questions. The group is older, and includes many blacks and Hispanics; of all the core Democratic groups, it has strongest sense of personal empowerment.
there's also color graph at the home page:

we're growing! "Enterprisers" (formerly staunch conservatives) remain our biggest ideological rival. Good stuff. Lots of info. ENJOY!
