Brexiteer?

If you want to take a cheap shot, why not aim broader with "politician"?

Your answer fails because it presupposes that everybody who wanted to leave the EU wanted to do so for outcomes which were unlikely or even impossible. Furthermore, the failure to achieve certain desirable outcomes by means of the soft exit delivered by our government may legitimately strengthen hypotheses about the achievability of such outcomes by a hard exit.

I do not question that there is a subgroup of Brexiteers who meet the test of having been wrong before the vote, proved wrong after it, and nonetheless more vehement now in the delusion that the thing they wanted was both desirable and possible, but for the word to meet the definition, it must be universal, not partial.
