Ken,
A decade ago I was a member of the Green Party, alas with their conversion to everything woke and adoration of NATO its impossible for me to recommend a vote for them.

Further, as with the Greens, NuNu Labour and LibDems in Wales, all Centrist, allegedly Left of Centre parties like their woke and pushing Transhumanism, so, the only thing that differentiates Plaid is their opposition to NATO and its the only reason I'll vote for them if an actual genuine Left vote not available, be it Communist, WPGB or a Lefty independent.
