How do we reach younger voters?

Leading conservative and libertarian thinkers I read on the internet are trying to come up with a message to appeal to younger voters in order to get them to vote Republican instead of Democrat. They reason that because Republicans stand for more freedom from big government control, all we have to do is emphasize that message, and young people will join up in droves. Surely, the argument goes, that message of freedom and liberty should have great appeal to younger voters. Not so fast. We also believe in personal responsibility and self control. Do we have to hide those beliefs in order to attract younger voters?
