re: #8 recusancy
I don’t see how Romney doesn’t get the nomination so this will matter in the general.
Romney is the “Trojan Horse” candidate - designed to reassure moderates and independents the GOP isn’t really so bad, when in reality, he’ll be beholden to the same debased base and obligated to enact their agenda (e.g. Ryan budget. Also see the actions of GOP govs like Walker, Scott, etc and imagine that on a national scale).
