The latest surveys of swing states in the election between Donald Trump and Hillary Clinton find the GOP candidate lagging in critical battlegrounds, with both nominees still sitting below 50 percent in expanded three- and four-candidate fields.

Clinton has a lead of 4, 9, and 10 percentage points in three polls of Pennsylvania published since Monday, reflecting a wider gap than what existed prior to several surveys concluded in the days leading up to last week’s presidential debate. In five polls completed between September 22 and 25, Clinton led by only one to three points.
