Currently, 50% of likely voters support Clinton and 38% back Trump, with 5% supporting Libertarian Gary Johnson and 2% backing Jill Stein of the Green Party. Clinton held a much slimmer 46% to 42% lead just three weeks ago.

The vote choice among all registered voters is 47% Clinton and 38% Trump. Clinton has a larger likely voter lead because only 5% of her potential supporters are considered unlikely to vote while twice as many possible Trump voters (10%) are unlikely to cast a ballot next month. This marks a change from Monmouth’s prior poll when 10% of registered voters supporting Clinton and 7% of registered voters supporting Trump were deemed unlikely to cast ballots.

“Clinton has increased her lead among all registered voters, but the main difference between this month and last month is that her supporters have become more enthusiastic, and thus more likely to turn out while Trump backers have become less likely to vote,” said Patrick Murray, director of the independent Monmouth University Polling Institute.
