"Well, I think that's a tragedy that is going to happen, with or without me," Robertson said on CNBC's "Closing Bell."
Robertson added that biotechnology stocks and Mexico look attractive right now, given the headline risk those areas face in the election. He said that investors are terrified Clinton will put the drug companies out of business and that the Mexican peso will likely gain after election day.
He said, however, that he is not backing Donald Trump and is instead supporting Libertarian Gary Johnson for president. Robertson previously donated to the campaigns of John Kasich and Jeb Bush, as well as the Republican National Committee, according to Federal Election Commission records.
Robertson said he is "crushed" that Mitt Romney did not win in 2012. Robertson called Libertarian vice presidential candidate Bill Weld a good friend that he has a lot of respect for and faith in.
While Robertson said Johnson is "a little more aggressive" on drug policy than he is, the founder of Tiger Management said he can "go along with" their policies. The billionaire said he is now focused on making sure the Republicans' "great senators and representatives" get reelected.
