Some Demographics of that new MA Poll

Much of Sanders’s support stems from voters who were not yet old enough to participate in that 2008 race. Among voters aged 18 to 45, he leads, 50 percent to 42 percent. But among the younger subset of 18-to-35-year-olds, his lead is a gaping 17 points. Voters in the older subset of that group are split evenly, according to the poll, rendering them a key bloc on Tuesday night.

Clinton continues to face a gender gap, winning easily among women with 55 percent of the vote, but trailing Sanders among men by eight points. According to Paleologos, women will likely account for between 56 percent and 60 percent of Tuesday’s primary electorate.

The only region of the state where Sanders leads is Worcester and the western counties. Clinton beats him everywhere else, most dominantly in Suffolk County, where the poll puts her 18 points ahead.

White voters prefer Clinton by a narrow margin, but non-whites break her way by 22 percentage points. She also leads among those without children, though Sanders holds a small edge among those with children.

Of the 21 percent of likely voters whose household includes a union member, Sanders holds a small edge.

Conducted Feb. 25 through Feb. 27 among 500 likely Democratic primary voters, the poll carries a margin of error of plus or minus 4.4 percentage points.
