Clinton, Trump take gloves off in White House slog

Harrisburg : Hillary Clinton and Donald Trump traded insults at opposite ends of the country Friday, taking their fight for the White House to rival battleground states and portraying starkly different visions of America.

One of the most divisive US campaigns in modern history is entering a new chapter with Republicans and Democrats having selected their nominees, leaving the candidates slogging it out before election day on November 8.

Clinton followed her historic acceptance speech on Thursday as the first woman presidential nominee for a major party with a rally in Philadelphia before embarking on a bus tour of Rust Belt states Pennsylvania and Ohio.

In Colorado, a key western state, her Republican opponent promised "no more Mr Nice Guy." He trashed Clinton's speech as "average," called her a liar and promised to end the migration of Syrian refugees.

"I'm starting to agree with you," the 70-year-old told supporters chanting "lock her up, lock her up" in Colorado Springs. "I'm taking the gloves off," he said. "Just remember this Trump is going to be no more Mr Nice Guy."

Just over 100 days before the election, Americans are being asked to choose between two sharply polarized visions -- and between two monumentally unpopular candidates.

"I can't think of an election that is more important, certainly in my lifetime," Clinton told supporters at the rally in Philadelphia.

The 68-year-old Democrat portrays Trump as a threat to democracy, and is seeking to both woo moderate Republicans repelled by the former reality TV star and shore up a coalition with progressives on the left of her party.
