Independent Greg Orman says he could change parties even after he has allied himself with Democrats or Republicans....
***
IOW, he is GOPe.
Wrong. He expects the Dems to retain the Senate, so his promise to caucus with the majority party is code for "I'm really a democrat". However he has to hedge his bet in the case the GOP takes over the Senate. Hence he makes a statement about being willing to switch after a couple of months.
You can see this when you listen to his rationale. Being with the majority is good for Kansas as it lets him get things done. So why should that change in a couple of months? Well, it must be if he gets a majority other than he expects and it isnt about being in the majority at all, really. Which it isn't.
