Alsobrooks up by 7 points. Harris up by 31 points (Biden carried the state by 33 points in 2020).
I wouldn't sweat Maryland. It is a deep blue state. Even Larry Hogan can't overcome partisan gravitational pull in a presidential cycle.
Alsobrooks is not as well known to voters as Hogan, but she has booked a ton of ad buys in recent weeks. That name recognition will change overnight and so will the polls.
