The Abolish Party ought not to be conflated with the abolish cause.
People are not single-issue voters, at least not to the extent that they would vote for a party with only one policy as though it were a referendum.
For example, a large proportion of voters inclined to support the Conservatives or Reform favour abolition. The same is true, to varying degrees, across the political spectrum. There are Labour voters who would scrap the Senedd, some Liberal Democrats, and perhaps even a very small minority of Plaid Cymru supporters.
Support for abolition is therefore spread across several parties, which helps to explain why the Abolish Party performed so poorly electorally: many of the voters sympathetic to its cause had already settled elsewhere. This is not to say that the abolish cause is a wholly unpopular one.
The thing is, when there has been organised campaigning on abolition, looking back at the 2021 election when the ATWA party were being promoted everywhere, they returned no seats in the Senedd and actually lost votes compared to the previous election
