With Rand Paul on the ticket with Trump, you end up with the same problem Romney had, the base not voting for 2 people closer to liberals than conservatives.
It’s not the same as the Romney problem, not at all. Trump and RandPaul both support the Constitution, neither one is afraid to campaign to those who’ve been less fortunate in life, and they’ll both speak up about things Romney avoided, like the incompetence that preceded the Benghazi attack. In a lot of ways, Trump’s message is a conservative message.
