The week in politics: Clinton, Trump draw battle lines - WDAM-TV 7-News, Weather, Sports-Hattiesburg, MS

Donald Trump and Hillary Clinton haven't been officially nominated yet. But already they're at each other's throats.

This week in politics showed what the tone of the campaign may be, and how tough a challenge Trump is facing.

"Hillary Clinton may be the most corrupt person ever to seek the presidency of the United States," Trump declared.

"He's written a lot of books about his business," quipped Clinton. "They all seem to end at Chapter 11."

That's a preview of what you're gonna see for the next several months in what promises — or threatens — to be one of the most brutal election campaigns in recent history.

Mississippi will be watching from the sidelines mostly. Pollsters continue to rate this state as solid red, as it has been for the past nine presidential elections.

This week a Quinnipiac poll showed a very tight race in Ohio and Pennsylvania — bad news for Clinton — but Trump falling sharply in Florida, now eight points behind. Florida is a must-win for him.

This hypothetical map generated by National Review shows why. Suppose Trump takes Pennsylvania and Ohio. He also picks up Iowa, New Hampshire, Virginia. He keeps all the Romney states from 2012. But he still loses the election, if Florida goes for Clinton.

And Republicans got a scare this week: a state poll showing Clinton leading Trump by four points in Arizona, which last voted for a Democrat for president in 1996. That Democrat — was Bill Clinton.
