Kudos goes to Liz Benjamin, one of the best political reporters in New York, for making the Senate elections a little easier to follow. She has a new online tool with a race-by-race rating of every Senate race in the state. That's what I consider pretty close to Holy Grail of state politics -- almost never will you see a knowledgeable non-partisan source prognosticate every race for a state legislative body.
Benjamin has seven toss-ups races. These include Republican-held seats in District 11, District 38 and District 40 and Democratic-held seats in District 3, District 48, District 49, District 58. Democrats currently have a supremely shaky 32-30 edge in the Senate. Assuming Andrew Cuomo is elected governor (a pretty safe assumption at this point) the lieutenant governor's office will remain in Democratic hands after the election. That means Republicans need a two-seat net gain to take back control.
The last two years in New York, though, have proven that there's a difference between nominal control and functional control. Democrats probably need a few more seats to govern how they please.
