What the GOP-e has done is to hunt up and corral wealthy former Democrat donors. They have misrepresented themselves as being the legitimate core of the party. The donors give them the money in the mistaken notion that they are real Republicans.
The result is we end up with a Romney and not a real Republican candidate for President, and a series of folks who run for senate who get plenty of money but who can't win.
We end up with Democrat-Lite, which will lose every single time.
