A Plaid Cymru spokesperson said the party "is unified in its mission to win" the 2021 election.The problem with Mr McEvoys argument is that his campaigning style is based on populist politics which involves making unfounded accusations about the ruling party and promises that he would find hard to keep.
Earlier this month the controversial politician withdrew his application to re-join the party he was expelled from.
Mr McEvoy has stood for the party in First Minister Mark Drakeford's Cardiff West constituency on a number of occasions, and says only he can win there for Plaid Cymru.
But the former Plaid AM says there are several people within the party who would rather see Mr Drakeford retain his seat and seek a coalition after the next assembly election in 2021.
Mr McEvoy told BBC Wales: "I think the issue really, is whether or not Plaid Cymru wants to win. I'd say the members do, but some people in authority at this moment in the party, do they want to win? Do they want to form a government? I know Adam Price does, I know I do.
"But I think there are some people who would probably be more comfortable being junior partners to Labour and I absolutely oppose that. I want to see Adam Price as first minister, I want to see a Plaid Cymru government but to do that we have to win Cardiff West. And I can."
Asked who he thought was acting in such a way, he added: "Why would anybody at the top of Plaid Cymru try to enable a Labour victory in Cardiff West? it doesn't make sense. The only explanation could be, would be, maybe there's a comfortable deal somewhere and some in Plaid want to be junior partners.
"I think you should ask the chair of Plaid Cymru, Alun Ffred [Jones], you should ask the chief executive. Those are the people who complained about me. Those are the people who want me out.
"Members didn't complain, those people did. And I know Adam wants to win, I want Adam to win, so let's get on with it. Let's get it done."
Plaid Cymru was a junior coalition partner to Labour in the One Wales government from 2007-2011, when Ieuan Wyn Jones served as deputy first minister.
Indeed it could be argued that like many populist (The Lib Dems often being guilty of this) ironically prosper in opposition and if given the reins of power will attack their rivals with the claims of Fake News but make no real difference because the power to do so lies elsewhere and thye do not have the finances.
I'd rather it was otherwise and there was power and finances to make the change, but to make promises that they can't keep is deceiving people.
I do not dismiss Neil McEvoy effectiveness in Cardifff West and god help us , the Labour Party have a lot to answer for.
However as in other parts of Wales it means people are not so much Pro Plaid (and independence) as Anti-Labour .
This means that Plaid have sometimes "succactually back square Plaid's Independence stance or it Progressive policies.
I am not a Plaid member , but it seems to me that already the prize of winning Cardiff West the home of two Labour AMs has blinded some members that it may not necessarily benefit the party elsewhere
