In a presidential race where the likely nominees of both major political parties have major disapproval ratings, is there room for a third choice?
New polling says maybe.
An NBC-Wall Street Journal survey this week shows 47 percent of registered voters would consider a third party candidate if the Republican and Democratic choices were Donald Trump and Hillary Clinton.
This weekend, the Libertarian Party will hold its convention to nominate a candidate. Front-runner Gary Johnson, the former governor of New Mexico, is polling at 10 percent in some recent surveys that include his name with Trump and Clinton.
While Americans have not elected a third party president, there have been some strong attempts: George Wallace won almost 14 percent in 1968. Ross Perot got 19 percent in 1992 and eight percent in 1996. Ralph Nader in 2000 got more than two percent of the vote, but that was enough to keep Al Gore from winning Florida, giving George W. Bush the presidency.
With the election still about six months away, talk of a viable third party candidate is still remarkably strong. But is there action behind the talk?
