My Congresswoman, Louise Slaughter, just died at age 88. I canvassed for her a couple times and have met her once or twice. She was a very good Congresswoman, very powerful within the Democratic caucus.
Typically, you should expect a Dem to win this district by about 15 points, so probably by 20 or more points this fall, given the likely 6 to 15 point swing we will in favor of Democrats. So this is a completely safe seat for 18.
