Attorney General Eric Schneiderman, largely unknown by voters, is “potentially vulnerable” at the polls, according to a poll released Tuesday by Siena College.

But pollster Steven Greenberg said it’s way too early to say the incumbent Democrat is in trouble since the election is six months away and the Republicans have yet to field a candidate. John Cahill, a former top advisor to Gov. George Pataki, is considering a campaign but has yet to formally announce his intentions.
