Albany Mayor Kathy Sheehan has taken a big step in her bid for a third four-year term. The Democrat on Tuesday turned back a primary challenge against Valerie Faust and now advances to November’s general election. Unofficial results from the Albany County Board of Elections show Sheehan with about 61 percent of the vote to Faust’s 35 percent. Sheehan spoke with WAMC’s Ian Pickus Wednesday morning.
