The decision by Rep. Anthony Weiner to resign today should help members of Congress all over the state sleep a bit easier tonight. Due to slow population growth according the the Census Bureau, New York’s House delegation will be shrinking from 29 to only 27 members for the 2012 election.

The likely result of any redistricting plan will be the lose of one Congressional district from upstate New York and the lose of one seat in the New York City metro area.

Normally this could force two Congressional incumbents to run against each other in a brutal campaign. But with Weiner’s resignation leaving the NY 9th district without an incumbent, it is almost assured to be a top target for elimination.

With Weiner gone and his 9th district free to be cannibalized, several New York City area Democrats should be feeling more secure about their re-election prospects.
