Trump vows to spend big on White House race

Donald Trump vowed to pour his own millions into the race for the White House Wednesday, refusing to be written off in the uphill battle against frontrunner Hillary Clinton.

Polls showed the Democratic nominee, who is vying to become the first female US president, still comfortably ahead of her billionaire Republican rival with just 13 days to go before Americans pick a new president.

The 70-year-old Manhattan businessman took heart, however, from a new survey that shows him with a two point lead in early voting Florida, and a slight narrowing in the race nationally.
