Our school systems are producing Dem voters as well. They serve as indoctrination centers--both K-12 and higher education.
They can be brought into the fold ~ and registration drives work. Obama proved that in 2008. He also proved in 2012 that you have to keep after the new voters as well. The Dems didn't do that.
I have it on good authority that within that bloc of 90 million untamed potential Republican voters, some of them are white people. I don't particularly care. Frankly, we need to bust the backs of the Democrats preying on the East Asians in this country ~ they're just criminals. Several million new Republicans are available if we bother to tag them.
