According to the poll, much of Glazer's margin is due to support from independent voters, a voting bloc the moderate Glazer has strove to cultivate. Among this subset of voters, Glazer leads Bonilla, 46-26.
Glazer also leads among those who say they have already cast a vote-by-mail ballot, 52-39. The spread is notable since the high number of ballots already returned appear skewed toward Democratic voters. Supporters of Bonilla's campaign have pointed to the voter data as evidence of strong support for their candidate, although, both maintain the same party affiliation.
Unsurprisingly, Republicans support Glazer by a 5-to-1 margin, according to the poll, while Democrats support Bonilla by a 2-to-1 clip. Meanwhile, wealthy voters are backing Glazer by double-digits, yet those earning less than $40,000 a year are split between the candidates, 40-40.
The campaign's top wedge issue, whether or not BART employees should maintain the right to strike, highly favors Glazer. Sixty percent of those survey say they should not, while 30 percent want to maintain the status quo.
