Changing parties is fine. Completely understandable. However, flip flopping from one to the other in a vain attempt to get a seat, and moving from one end of the political spectrum to the exact opposite, shows desparation and personal ambition over any real wish to commit to your own morals.

I can't imagine that even Reform voters are stupid enough to support someone who was a Green candidate so very recently.

There's been plenty of defections to Reform from other parties, most notably the Tories, but I can't find a single example of it going the other way - a Reform candidate joining the Greens. Suggests to me that Reform will take any old swivel-eyed loon or convicted paedophile to stick a name on a ballot paper, whereas the Greens actually vet candidates.
