美国有线新闻 CNN 美国总统大选日 希拉里特朗普选情分析（在线收听）

First up, Election Day in America. This is it, the day when American voters finally get their say who becomes their next leader. They are also voting for all U.S. representatives, and about a third of U.S. senators, as well as state and local officials.

But the spotlight is on Republican presidential nominee Donald Trump and Democratic presidential nominee Hillary Clinton. One of whom is certain to take the Oval Office.

Several recent national polls indicated that Clinton had a slight advantage between three to four percentage points about likely voters. This is a close race and both candidates have a path to victory. Voters won't be directly choosing their president. What they're doing is choosing electors to vote for them. The higher a state's population, the more electors it has.

CNN's Electoral College map gives an idea of how things could go today. But again, these are estimates based on polls, previous votes and early votes.

JOHN KING, CNN CHIEF NATIONAL CORRESPONDENT: You have to say advantage Clinton as we headed to these final hours, and this big national lead is why. Four points for Secretary Clinton, 46 percent to 42 percent heading into the final week and the national CNN poll of polls, that compares favorably, a better lead than President Obama had at this point in 2012, a bigger lead than George W. Bush had at this point in 2004, the last time Republicans won the presidency.

National leads though don't always win presidential elections. We pick our presidents state by state. So, you look at this map and here's the question. In this frenetic final day, is there a path for Donald Trump?

Well, let's start here. Hillary Clinton thinks with early voting, she's going to get Nevada. If she does, that puts her over the top, 274 in our count.

They also think in the Clinton campaign, again this is a hypothetical scenario, they think they're going to win North Carolina, again because of early voting. The Trump would push back, but let's give it to her just for the sake of this. And Republicans in New Hampshire are worried, they think over the weekend, that state is started to break.

What if Hillary Clinton wins all those? A hypothetical. But if she does, can Donald Trump still win? That's why he's targeting the big, blue states.

Donald Trump must win Arizona for starters. That would give him to 215. No brainer, must win Florida. If Donald Trump loses Florida, forget about it, game over. But if he wins Arizona and Florida, can he take away the blues and come back?

That is why in these final days, Donald Trump is saying, I'm going to take Pennsylvania, and I'm going to take Michigan, that would do it. Now, 1988, 1988, the last time those two big blues went red. Democrats say, "Dream on, Donald." His campaign says, "Watch".
