Leo Canty is a strong advocate — for labor, for Democrats and, for much of the last year, for why Windsor deserves its own House district. One of the overlooked ironies of last night’s primaries is Canty’s potential role in denying Windsor its victory.

At his urging, the map-makers drew a district that is dominated by Windsor, though reaches into Hartford, and is dominated by black voters. Here’s the twist: Windsor fielded two candidates and Hartford one, resulting in the Windsor vote being split Tuesday in the Democratic primary.

Canty, who is white, was one of the two Windsor candidates for the seat he pitched as a solid black district. An AFL-CIO officials and longtime Democratic leader in Windsor, Canty couldn’t pass up the chance to run himself in the Democratic primary.

On Tuesday night, unofficial results showed Canty in a tie with Brandon McGee of Hartford. A recount is coming.

Oh, the irony if the Windsor seat goes to Hartford — or if a white guy carries a district created as a black district, at his urging.
