The basic premise is sound—that Trump has a vendetta against Obama.

Then, failing to get the GOP nomination, Trump goes indie and all the birther talk dissipates as he directs his attacks at the GOPer. With the GOP irreparably splintered, Obama glides to a landslide reelection.

I think the GOP is probably already irreparably splintered.

The “senior” GOP congress is certainly trying to control the new freshman members.

How would the GOP deal with a Tea Party candidate.

That, IMHO, is not out of the question.
