Actually, upon further inspection, I don't buy this poll for a second.
I'm from Montgomery County. I know the area well enough to say that there's absolutely no chance Jealous has a 35 point lead in Montgomery while only leading in PG by 13 and Baltimore by 6. The Montgomery number sounds incredibly optimistic for Jealous while the PG and Baltimore numbers sound the opposite. Back in 2014, Anthony Brown won PG by
70 points and Baltimore by
54, while only winning Montgomery by 25. Either the numbers in the poll are wrong or that's an absolutely remarkable reversal. You don't just go from losing a county by 70 points to losing it by 13 and somehow, simultaneously, go from losing a different county by 25 to losing it by 35. That's just illogical.
Those numbers in mostly black, inflexible PG and Baltimore aren't just surprising, they're downright unbelievable. Same with the numbers in moderate white Montgomery, which Jealous is a fairly bad fit for.
