You can all say that Rand Paul's tax plan is gonna be the single worst one in history. But personally, I think that Ted Cruz's one will be even more worse and hurtful, that is, if he's ever gonna release one.
To be honest, Rand's tax plan hit me right in the heart as I really believed in this guy. Still, he's one of the saner on almost all policy positions. So he's still in my top 4-5 top tier.
Paul's probably the best Republican on foreign policy, but one of the worst on economics. The thing is, if he did become president, he'd pursue his foreign policy while congress would water down his economic policy.
