8 years later we've had no major movements, and running one of their own kind isn't going to attract further large groups of Democrats to the Republican brand. What it will do is alienate legitimate Republicans.
This is not rocket science ~ it's politics. You may be willing to give away our top slot to a leftwingtard again, but I"m not, and we don't have to anyway. You don't see the Democrats doing that!
In your la-la world I'm not surprised you find that true.
