Strictly my speculation ... Mark Kelly just posted this on Zombie Twitter:
"My background is a bit different than most politicians. I spent my life serving in the Navy and at #NASA, where the mission always comes first. Now, my mission is serving Arizonans."
That last sentence has me wondering if he's out of the #Harris VP sweepstakes.
@GeezerWench Thank you for sharing. I think your citation clinches it.
