Yep. Some will use any issue to claim that the answer is ... a 3rd party. If they had a 3rd Party many would not agree with what is going on and form a 4th party ... and on and on. The better option is to work within and persuade as many as possible.
It takes a large group of Americans to win a Presidency and there is no way all those people will ever agree on everything. All we can do is fight and persuade.
And there will always be some who will use any justification for staying the course and continuing with the same failed strategies.
TThe sooner the gop joins the whig party on the ashheap of history, the better.
