It was unethical for Huck to stay in the 2008 race and play spoiler for Romney and ensure the McCain nomination.
It was motivated by his anti-Mormon bias.
You don’t have to be pro-Romney to hate the tactic and the motive.
I was happy that Huckabee stopped Romney in 2008. McCain at least gave us Gov. Sarah Palin. I wished Romney would have gave up running in 2008 and I hope he never runs again.
