These blue avatars are making sense.
I'm a hard pass on Grant "snore" Woods.
I am intrigued by both Ruben Gallego and Mark Kelly.
Ruben Gallego is an up-and-comer. He is a progressive but seems earnest and non-controversial and has a good personal profile. Plus representation matters and the Dem. ticket would benefit from a boost in Latinx representation.
Mark Kelly has a lot of residual goodwill as the husband of Gabby Giffords. Had they not tried to assassinate Giffords, she would likely be in the Senate already (having defeated Flake in '12) and also a major contender for the Democratic Presidential nomination in 2020. I am very moved by the Kelly/Giffords advocacy and think that Kelly's bipartisan outsider profile could be an advantage.
I would be inclined to encourage a robust primary to determine which is the more capable, energetic candidate. As long as they don't get nasty with each other... but it seems Kelly may be looking for a "cleared field" which I'm not sure is either possible or advisable.
