There's an article on Huffington Post this morning quoting Carlos Gutierrez, hispanic advisor to the Republican party as to why hispanics were so terrified of Romney and the Republican party: http://www.huffingtonpost.com/2012/11/11/carlos-gutierrez-mitt-romney-latinos_n_2113622.html
They weren't the only ones terrified. So were negroes, gays, secular-minded people like me, women, anyone who sees the danger of further uniting religion and the state, etc.
One commenter sumed it up well by writing: "Is there actually anything the repubs are for that doesn't involve being 'anti' something?"
Too which another commenter replied: "Let's see: anti-gay, anti-immigration, anti-reproductive rights, anti-voting rights, anti-middle class, anti-union, anti-medicaid, anti-medicare, anti-education, anti-science. OK, I'm going to run out of space."
That pretty well sums it up.
