Donald Trump Leads in National Poll on Eve of First Debate

Donald Trump has a slight edge on Hillary Clinton on the eve of the first presidential debate, according to a Bloomberg Politics poll released Monday. At the same time, two battleground states have tightened, cutting Clinton's lead to one percent.

In the Bloomberg Politics national poll, Trump and Clinton each get 46 percent in a head-to-head contest. But other candidates will be on the ballot in November, and with Libertarian nominee Gary Johnson and the Green Party's Jill Stein included, the Republican takes the lead, with 43 percent to Clinton's 41 percent. Johnson lags in third with 8 percent.

This represents a steady gain for Trump on Clinton in the past two months. In August, Clinton had a 6-point lead in the two-way race, and a 4-point lead with third-party candidates included. In June, she had a 12-point edge on Trump, even including Johnson.

Perhaps most surprisingly, this poll showed millennials swinging to support the Republican. Among likely voters under 35 years old, Clinton takes 50 percent to Trump's 40 percent, a large decrease from the Democrat's 29-point lead among the young in August.

Another poll released Monday, this one from CNN/ORC, shows Trump and Clinton neck-and-neck in two battleground states, Colorado and Pennsylvania.

Trump leads in Colorado, with 42 percent to Clinton's 41 percent, with Johnson at 13 percent. This one percent lead falls well within the poll's 3.5-point margin of error. Clinton takes Pennsylvania just as narrowly, with 45 percent to Trump's 44 percent, and Johnson back at 6 percent.

Whites with college degrees back Clinton heavily, while those without them favor Trump. This education gap is larger than Clinton's lead among women or minorities.
