Not only are Johnson's expenditures a gray area ethically in terms of campaign finance, but they also may have to be reported to the Internal Revenue Service.
"If they're personal expenses, if you have others basically spend money on your behalf, you're supposed to report that as income on your own income taxes," says Jon Pratt, executive director of the Minnesota Council of Nonprofits.
But in Johnson's view, that wouldn't be necessary because the expenses are for the campaign. "As I said, I'm running all the time—that's my life."
