ALBANY COUNTY — County Executive Michael Breslin signed the legislature’s redistricting map, which changes the lines of the county’s 39 voting districts to reflect population changes in the 2010 census.

The town of Guilderland will now have a fifth district.  And the town of New Scotland will have three partial districts, each of which it will share with Bethlehem, rather than the current two — one shared with Westerlo, and one with Bethlehem.

The plan had been criticized by Hilltown residents who didn’t want to be divided and Albany residents who said minorities weren’t adequately represented.  (Go to www.AltamontEnterprise.com and look under “archives” for May 26, 2011 for earlier coverage.)

Michael Mackey, New Scotland’s town attorney and chair of the town’s Democratic Party, said that he will seek election in the 38^th District, which has been held by Charles Houghtaling, who is not seeking re-election in November.  The district had covered most of New Scotland and all of Westerlo, but now covers most of New Scotland and some of Bethlehem.

“It was really after the redistricting was completed,” Mackey said of when he made a final decision to run.  If elected, he would remain chairman of the New Scotland Democratic Party but would relinquish the town attorney’s post.

A partner in his law firm, Feeney, Centi, and Mackey, Dennis Feeney, is seeking election in Guilderland’s new district, Mackey said yesterday.

Feeney, a Democrat, had represented Guilderland’s 30^th district in the county legislature before moving to the 29^th District.  He challenged Republican Lee Carman for that seat in 2007 and lost.
