If someone from inside the party is saying to you plainly...
"The party is putting us into the worst possible situation to compete possible, and it appears that corruption may be the reason."
and you are still looking past that to the GOP doing what it can to lay the blame...
That says quite a bit.
If you want to be able to put anything like progressive ideas into a position where they can do folks some good, it is far less likely that you will be able to do so when a party is taking a crow bar to the legs of any attempt to even be able to compete in statewide elections.
If you don't believe that calling that out will put you into a better position to actually solve problems, that is another problem that anyone who is trying to move things forward will have to address before even being in a position where they might get the chance to do some good.
