It could go smoothly or not so smoothly. It depends on how the GOP, Romney, his campaign, and how his family handles and reacts to it all, IF he gets the nomination. Obviously, the wierdoes will come out, and even legitimate rational people will come out with opposition. The Dems will have to take advantage of some of that.
What is intriguing is pitting the Romney Family against Klinton. Klinton really doesn’t have a family. America would see two very different families. This is something the GOP is going to consider IF, for example, it comes down to Romney and Rudy. My fear is that the GOP will be so scared of Klinton that it will choose Rudy.
My fear is that the GOP is so divided that Rudy and the RINO faction of the party will win the nomination with no more that 30% support.
