The Washington Post polled Maryland voters' 2016 Democratic primary preferences:

Clinton 60%
Biden 17%
O'Malley 7%
Cuomo 4%
If you want to expand it to all registered voters, the numbers are:
Clinton 47%
Biden 15%
O'Malley 6%
Cuomo 6%
Yes, that's right. O'Malley is in third place and single digits in his own home state.
Also asked:
Do you approve of O'Malley's job performance as governor?
registered voters: 49% approve / 44% disapprove
Democrats only: 68% approve / 24% disapprove
If O'Malley was the 2016 Democratic presidential nominee, would you vote for him in the general election?
registered voters: definitely yes 17% / maybe 40% / definitely no 39%
Democrats only: definitely yes 29% / maybe 53% / definitely no 16%
Yikes, that's pretty pathetic. His overall 49% / 44% approve / disapprove numbers aren't awful, but he is a Democratic governor in a Democratic state. He should be doing better than that. Looks like those numbers are inflated by the fact that he has a "D" next to his name. But even many/most of those Dems who approve of his job as governor don't seem to think he's presidential material.
