Republican Rep. John Katko holds a double-digit percentage point lead over his Democratic challenger Colleen Deacon, a Time Warner Cable News/Siena College poll found.

The poll shows Katko leading Deacon in the 24th congressional district race, 53 percent to 34 percent.

The central New York House district is one of the top-tier battleground seats in the upstate region, with voters handing only a single, two-year term to representatives in Congress for the last several cycles.

But Katko, a freshman lawmaker, is prevailing in a district in which Democratic presidential nominee Hillary Clinton is leading Republican Donald Trump by 12 percentage points. Clinton leads Trump among 24th congressional district voters 45 percent to 33 percent.

At the same time, U.S. Sen. Chuck Schumer is handily defeating his Republican rival in the district Wendy Long, 62 percent to 28 percent.

And President Obama holds a majority favorable rating in the district, 54 percent to 43 percent.

Katko himself remains popular, with a 51 percent favorable rating, including 50 percent among independent voters. Deacon, meanwhile, has a 32 percent favorable rating, 41 percent of voters don’t know enough about her or have no opinion.

Voters appear to lean to the left on some issues in the district, including the Affordable Care Act — a narrow majority support keeping it and improving the measure — as well as support for creating a pathway to citizenship for undocumented immigrants.

Voters, however, are also split on which party should control the House of Representatives: 43 percent back a Republican majority, 46 percent want it flipped to Democratic control.

The poll of 655 likely voters in the 24th congressional district was conducted from Sept. 22 through Sept. 29. It has a margin of error of 4.8 percentage points.
