Horns- I hope you aren't a democrat with that belief.
The only demographics that the dems lead in (educationally) is graduate degrees and High school degrees/high school dropouts. And I can promise you there are way more high school degrees/drop outs then grad degrees.
If we got rid of the bottom 50% of the eductated voting population Republican's would dominate. So, remember, glass houses and stones and what not.
If you are not a dem then ignore everything I just said.
