U.S. Sen. John McCain’s Tucson campaign office is opening today without the man of the hour.

McCain wasn’t able to get to Tucson in time for the opening because of flight delays, said Brian Rogers, campaign spokesman. In his stead, he’d hoped to have Congressional candidate Jonathan Paton fill in to address the party. But Paton had personal business to attend to in Phoenix, so he was heading the wrong way on I-10 when the party was underway.

That sent campaign staff scrambling less than two hours before the event.

Tucson Mayor Bob Walkup and car-dealership owner Jim Click spoke to the crowd of about 150 people while the senator waited out a storm in Dallas.

McCain is due back in Tucson in a couple weekends, Rogers said.
