On the eve of the first presidential debate, a new Morning Call/Muhlenberg College poll shows a narrow gap between Democrat Hillary Clinton and Republican Donald Trump amid rising support for Trump within his own party.... In a four-way matchup, Clinton leads by 2 points, at 40 percent to Trump's 38 percent. Libertarian Party candidate Gary Johnson dropped to 8 percent — down from 14 percent a week ago — and Green Party nominee Jill Stein went from 5 to 3 percent.
