So, in your learned opinion, who exactly are the wingnuts in this place?
Are they the ones supporting a candidate during the primary process, with the idea that they will ultimately support whichever candidate wins the GOP's nomination in order to defeat the Democrats.
Or are the wingnuts the ones saying that if the candidate of their choice fails to win the GOP's nomination, the will take action (vote third party) or fail to take action (stay home and not vote) and by doing so facilitate a victory for the DNC candidate?
The latter.
In fact, your description reads almost like a textbook definition of a wingut.
The latter.
