GOP, Dems, Keep Wary Eye on Third-Party Presidential Contenders Steve Herman WHITE HOUSE - In next year's U.S. presidential election, most voters will have one or more additional choice beyond the nominees of the Democratic and Republican parties. And there are indications that a relatively obscure third-party candidate has the potential to decide the election's outcome. That happened in 2016 when a smattering of votes in key battleground states in the Midwest enabled Donald Trump to defeat Hillary Clinton, who won the overall popular vote, thus capturing the tabulation for the Electoral College. Like Clinton, then-Vice President Al Gore, also a Democrat, saw his Oval Office dreams shattered in 2000 when Green Party candidate and consumer activist Ralph Nader tipped the extremely close election of 2000 in favor of Republican George W. Bush. .
