That DOT number is not in the FMCSA’s data base, so they either made it up, or registered a motor carrier company that was then removed from their system.

I went to one for a candidate for the House district I lived in a few election cycles ago, It was mostly stump speeches and other “rah rah we’re gonna win!” style pontificating. But one thing I did not expect and I actually found interesting was the house candidate spent a lot of time introducing other local politicians that were in down ballot races in the district. City council seats, education board seats etc. That turned out to be really useful, because it meant I got to meet/ hear from candidates who I either had no idea existed or who were just a name of a flyer before then. I suppose that experience may not transfer to a national candidate rally though.
