Will the Republicans split into the Libertarian Party and Christian Party?

[Zarn]

The Maine senators aren't libertarian. Republicans aren't joining the Dems. They are becoming independent or libertarian. They are upset over the spending, so the solution is not joining the party of care free. Some former independents may have identify as Dem from the election cycle, but that will die down over time.

[Zarn]

More of them independent than libertarian, although there is a slight rise in libertarian thought, due to the Sarah Palin fallout.

Really, most of it isn't reregistration, just people identifying themselves as something else.

Then you had some independents claim to be Dem. So, it looks like Republicans are jumping to the Dems.
