Oh no. He will get .0000002 percent of the vote. Let him do it. I completely forgot about him even running. He is hardly a burp.
If he's lucky.
Libertarians have routinely been known to take the margin of victory between GOP and Democrat candidates. Running as a Libertarian, Bob Barr gave both Indiana and North Carolina to Zero in 2008 (IN hadn’t gone Dem in a Presidential race since 1964). In the race for the seat Gabby Giffords holds in AZ, she only defeated Republican Jesse Kelly with a mere plurality in 2010.
Gary Johnson could prevent the Republican candidate from winning New Mexico (which is a state we need to win), even if he only got, say 5% or so, which he probably will.
He’s popular among libertarians. If the Ron Paul people don’t like the GOP nominee, they could bolt to Johnson if he runs.
That will make it harder for the GOP to beat Obama.
