Clinton leads Donald Trump in the head-to-head match among likely Pennsylvania voters, 49-42.
Including third-party candidates in the poll, Clinton maintains a seven-point lead, 46-39, with Libertarian Gary Johnson polling at 6 percent and Green Party candidate Jill Stein at 3 percent.
A Quinnipiac poll released last week showed Clinton with a similar six-point lead in both head-to-head and four-way polls of likely Keystone State voters. Siena/NYT Upshot has not previously polled the state's likely voters on the general election.
The Siena/NYT Upshot poll surveyed 824 likely Pennsylvania voters via live telephone interview from Oct. 23-25, and has a margin of error of plus or minus 3.4 percent.
TPM's PollTracker Average for the presidential election in Pennsylvania shows Clinton leading Trump, 47.6 to 41.9.
