I voted for McCain only because of Sarah Palin. I suspect McCain would have lost by more than he did with this Uniparty douche on the ticket instead of Palin.
Maybe....Sanford would have been seen as more serious, more credible. I like Sarah Palin, but the media created a caricature of her that still lingers with her image today.
Sanford would have probably given McCain NC, OH, NV and NM because of his economically conservative views.
Remember, social conservatism essentially died in 2006 when the MSM tied the Evangelicals with Ted Haggard and the Iraq War. There is a reason why Mike Huckabee and Rick Santorum will never be president, social conservatism is waning. Economic conservatism is the way to go.
However, Sanford is violently anti-Trump.
