Larry Sabato - he is so in bed with the DNC - I don’t trust anything of his predictions intended to influence elections.
I'm not sure you're right about that but in any case Sabato has a pretty good reputation for accuracy. His predictions are very accurate. I really wish that Michael Barone would do an equivalent evaluation of the races but if he has I haven't found it.
And note that we are carrying 4 different "experts" at this time. If there is a Dem bias in any of them it will stand out.
