From Politico on August 26:
“Libertarian presidential candidate Gary Johnson’s campaign is spending nearly $1 million on advertising in four battleground states, plus Oregon, Utah and his home state of New Mexico, as part of a new advertising blitz.
“The new ad spending is the first indication of where Johnson is hoping to compete in the coming weeks. The former New Mexico governor’s campaign is spending $806,195 this month on radio ads in Colorado, Iowa, New Hampshire, New Mexico, Oregon, Utah and Wisconsin, according to a media buying source.
“‘The campaign also is spending money on digital billboards as part of its advertising push’, said Johnson campaign spokesman Joe Hunter. ‘Additional advertising is expected through Labor Day, bringing the total spending to at least $1 million’, he said.”
