美国有线新闻 CNN 美国大选进入两个月倒计时 特朗普支持率领先希拉里（在线收听）

This show's date is Thursday, September 8. That puts it exactly two months before the 2016 U.S. presidential election.

Here are the candidates: businessman and TV personality Donald Trump is running on the Republican ticket. Former U.S. Secretary of State Hillary Clinton is running on the Democratic ticket. Businessman and former New Mexico Governor Gary Johnson represents the Libertarian Party. Retired medical doctor, Jill Stein, represents the Green Party.

There are three presidential debates scheduled starting later this month. They'll include Mr. Trump and Mrs. Clinton, but at this point, you're unlikely to see Mr. Johnson or Dr. Stein included. Why? The Commission on Presidential Debates which sponsors and produces the events requires candidates to poll at 15 percent or higher to participate.

According to the latest CNN/ORC poll conducted early this month, Donald Trump has the lead with the support of 45 percent of likely voters.

Hillary Clinton had the support of 43 percent. Gary Johnson had 7 percent, and Jill Stein had 2 percent.

We'll have a lot more coverage in the days ahead, and you'll find additional info about the candidates and the election in the extra credit resources section of CNNStudentNews.com.
