(Obligatory include the actual number in the title comment)
Johnson could conceivably win a county or two with numbers like that. Fascinating.
More than likely inflated. A PPP poll of New Mexico prior to the 2012 election has Johnson at 24 points. He ended up getting less than 4.
That poll was taken in December of 2011. It's not comparable to a poll taken a month and a half before the election. His numbers may go down, but they won't drop to 4%. Hell, I doubt his nationwide numbers will go down to 4%.
