ALBANY -- This year's presidential candidates both call New York home, but it hasn't made much of a difference in state-level polls.

Presumptive Republican candidate Donald Trump trailed Democrat Hillary Clinton by a 23-point margin in a Siena College poll released Thursday, with 54 percent of registered New York voters backing Clinton and 31 percent backing Trump.

Trump, the Manhattan businessman, has repeatedly said he expects to compete in his home state. Clinton, the former secretary of state, represented New York in the Senate and resides in Chappaqua, Westchester County.

The candidates' New York ties, however, haven't shifted the polls in the state, which hasn't backed a Republican since Ronald Reagan in 1984.

Take 2012: In June, Barack Obama led Republican Mitt Romney by 24 points in a Siena poll, with 59 percent supporting the Democratic president. In June 2008, various polls showed then-candidate Obama with anywhere from a 14- to 31-point lead over John McCain, according to RealClearPolitics' poll tracker.

"Despite the fact that we have the native New Yorker against the adopted New Yorker, we're not seeing a whole lot different this cycle at this time than we saw four years ago or eight years ago with both campaigns involving non-New Yorkers," Siena pollster Steve Greenberg said.

Republican candidates face a large enrollment disadvantage in New York.

As of April, the state had 5.3 million active enrolled Democrats compared to 2.6 million Republicans, according to the state Board of Elections.

Neither Romney nor McCain were ultimately able to make New York competitive: Obama won in 2012 with 65 percent of the vote. In 2008, he got 63 percent.

Erie County Republican Chairman Nick Langworthy, a co-chair of Trump's New York campaign, said Trump's message -- particularly on trade and the economy -- is "selling very well with middle-class voters" that had difficulty connecting with Mitt Romney four years ago.

"I'm not ready to declare New York in play, but I do think Trump is going to perform a great deal better than Mitt Romney or John McCain," he said.

While the gap between the Democratic and Republican candidates remains similar to previous cycles, Clinton and Trump have lower favorability ratings in New York than the previous candidates.

Thursday's Siena poll showed 28 percent of New York voters had a favorable view of Trump, compared to 68 percent unfavorable. Clinton had a near-even split: 50 percent favorable, 47 percent unfavorable.

In June 2012, Obama had a 59 percent favorable rating in the state, with 38 percent unfavorable. Romney was at 35 percent favorable, 56 percent unfavorable.

For its most-recent poll, Siena polled 803 registered voters in New York from June 22 to 28. The poll has a margin of error of 4 percentage points.
