“Now this isn’t a call for a third party. Third parties are doomed to failure; the system is geared toward a two-party system. But what the Republican Party does need is a housecleaning. Call it a purge, if you must. But do it.”
The Republican party could become the third party.
My understanding of American political systems is that when the controling party see's a 3rd party gaining control, the party currently having control will insinuate the planks of the rival party's platform into their own.
Depending on the magnitude of change, the party having control might have to change its name.
The question is whether or not the party in control changed to accommodate their constituants, or whether they morphed; the net result is still a two party system.
“The Republican party could become the third party.”
Yeah, we’ll have the Democrats, the Liberal Democrats and also a few Republicans.
