Because she knows that Palin cannot win. Sorry to say because I love Sarah, but she is not likely to win. The people would pick up immediately on Christie and he would get wide support. Palin, on the other hand has been marginalized by the media and by her own actions. I also don’t think that she’s going to run. Ann Coulter is right about the current list of candidates. There isn’t anyone who can beat FUBO.
I’m warming to a Trump/Christy ticket. I think it would be a winner. There is one obvious thing here though, they’re both from the same area of the country. Trump, NY and Christie, NJ. Although, I don’t think this particular issue means as much as it did back in the day, when, in 1960 JFK, a New Englander, picked LBJ, a Texan.
