Before everyone anoints him /ourguy/ you should know that he's Cruz's guy in Iowa, he's Bob Vaanderplat's congressional water-boy, and he's beholden to the Terry Branstad faction of the Iowa GOP. He's notorious as the state's premier talk radio attention whore.
Possibly. He already has three Rep challengers for his 2020 primary. His committee seats will most likely go to an out of stater though.
Most likely just another DARPA pork-barrel bonanza. To be honest they have a pretty dismal track record when it comes to bringing gee-whiz concepts into the operational inventory. Stuff like the Land Warrior System, the autonomous mules, the Star Trek bio-beds for casualty treatment etc. New Congress = New Budget = Everyone's out for a piece of the pie.
Cuz Pepe feels good man.
