MIAMI/WASHINGTON, Nov 9 (Reuters) - Fed up with Washington and feeling left behind, supporters of Republican Donald Trump upended the U.S. presidential race, electing a political newcomer they say offers the country a shot at dramatic change.

Once dismissed by Trump's Democratic rival Hillary Clinton as "deplorables," supporters interviewed on Tuesday shrugged off his late-night tweeted insults, allegations against him of sexual misconduct and dire warnings from many in the Republican establishment that the businessman-turned-reality-television-star would throw U.S. economic and foreign policy into disarray.

The economy, terrorism and healthcare ranked as the top three concerns facing Americans casting ballots in Tuesday's election, according to an early reading from the Reuters/Ipsos Election Day poll of about 35,000 people.

"The freedom-loving Americans pushed back against the elites and the globalists. They might win in the long run, but we're not dead yet," said Andrew Dye, 48, of Dexter, Michigan.

"I think this big country is getting a little too far left a little too quickly and some people finally woke up and said enough," said Dye, a partner in a small management consulting firm.

Cuban-American Sarah Gird, 67, described herself as an independent who had felt let down after twice voting for Democratic President Barack Obama.
