First, I didn't know there was any presidential chatter around Utah Sen. Mike Lee.
Second, even if there is/was, he's not interested.
Via The Salt Lake Tribune:
Asked last week whether Lee would consider his own bid for the Oval Office, an aide responded: "No dice."
Lee has teamed up with Rand Paul and Ted Cruz on high-profile issues this year, but never really provoked the buzz or chatter that the other guys have.
