It’s one of the largest unknowns of this election season.

Just how involved will Bernie Sanders be in down ballot races for Democratic candidates.

According to Seung Min Kim of Politico, a number of Democratic nominees would welcome Sanders with open arms. Among them is Katie McGinty.

“[This is] not something we’ve talked about or planned yet, but she’d absolutely campaign with him,” McGinty Communications Director Sean Coit told Politico.

Sanders support would be particularly helpful considering that a debate has emerged over which candidate is really closest to Wall Street. Campaigning with the man who pledged to break up the big banks would certainly settle that argument.

One big question, though, is whether Sen. Sanders will deign to pitch in for McGinty. As Kim notes, Sanders so far has only stumped with former Wisconsin Senator and noted progressive Russ Feingold. In the past, he’s even been reluctant to support those that stuck out their necks and endorsed him in the primary.

It’s possible Bernie doesn’t believe McGinty deserves his support.
