It's an endorsement that could prove to be significant for Janey within the Latino community.
"Number one, does the endorsement carry clout? And number two, is the endorsement in a subset of voters that has a high undecided [rate]," said Suffolk University pollster David Paleologos. "In this case, the answer is yes, to both."
Paleologos says with polls showing one of every three Hispanic voters is undecided, the Arroyos, with a proven track record of grass-roots campaigning, could help sway votes.
But not everyone agrees.
"For me, it's not just about identity politics," said Patricia Montes.
Montes is the executive director of Centro Presente, a Latino organization fighting for immigrant rights. She says she is still undecided.
