According to this site, as of Friday there is 40% Dems and 30.5% Repubs. It’s not as far off as you think.
Even if that’s true, it’s a 2% high D voter sample to get a 2 point Cankles lead. And we don’t know the M/F split.
Nope, ain’t buyin it. Minion won this state by 2.2 points, so at best this poll is 4 off.
