When elections are this close, you can look to all sorts of different areas that were causal. Rock Strongo is right: Romney on campus would have been heckled mercilessly, and it would have resonated negatively. Still, one terrible consequence of NO ONE campaigning on college campuses is that then these students don't hear another viewpoint; and they are the future leaders. Conservatives need accepted surrogates talking to the youth, as well as talking to the various Democratic constituencies; just so they hear another view. I also suggest running 'PSA' like messages similar to Schoolhouse rock,etc. funded by the GOP or GOP front groups on TV, internet and social media - start NOW!
