If Jason Kander wasn't doing things to try to raise his profile, including things that strongly hint at presidential ambition like trips to Iowa and New Hampshire, then no one would be talking about him either.
Yeah, the guy is just a former state SoS who lost a race he was considered by many to have in a bag. There's no way he can try seriously in 2020.
Lolwut. When was MO ever considered to be "in the bag" for the DSCC? Kander took a race that was on nobody's radar, and with a stellar campaign made it an actual horse-race. And then he ended up running ahead of Clinton by 16 points, only losing by less than 3 points. He'd be a Senator right now if not for how unpopular HRC was in Missouri.
