I received my reminder postcard for the primary from the registrar of voters and noticed that my ward had changed although I have not moved. I used the ward lookup function on the city website (http://www.cityofnewhaven.com/aldermen/index.asp) and it said my ward was the same as last year. Then I looked at the actual map on the same page and saw that, no, it really is what the postcard says.

One of these must be wrong. I'm assuming it's the website, but I guess I won't know until I actually go the polling place on the card, but who knows? (FWIW, I was in Ward 7 and the map and postcard say it's now Ward 1.)
