A new Siena College poll shows the race tightening in the 25th Congressional District, with Democratic incumbent Louise Slaughter leading Republican challenger and Monroe County Executive Maggie Brooks 49 to 44 percent.

That compared to an earlier Siena Poll in late September where Slaughter led 52 to 42 percent.

The Voice of the Voter poll was done on behalf of the Democrat and Chronicle, 13WHAM-TV, WXXI and WDKX.

The survey shows that Slaughter leads 69 to 24 percent in the city of Rochester, which is heavily Democratic, but Brooks leads 50 to 43 percent in the rest of the county, where Republicans outnumber Democrats.

The latest poll had a margin of error of plus or minus 3.5 percentage points.
