For Warren, it depends what she's looking for. If we're in a recession, and she needs a truce with Wall St, Booker makes the most sense. If she were to want to make climate change 1 of her signature efforts (which I kinda doubt), Inslee would make sense. Given her age, if she wants to look for the next young gun with long term potential, Buttigieg makes sense. Of the 3, Inslee makes the least sense from an EC perspective. He doesn't help anything from a geographic perspective, nor would he help any with independents or never Trumper Pubs. I think Booker helps her the most with independents and never Trumper Pubs, Buttigieg after that. The reason I say Booker is we're probably heading into rocky economic waters. We're already in a manufacturing recession. Neither Wall St nor the banks care for Warren in the least, though she is at least much more tolerable than Sanders. Booker is a former Wall St guy who could help make Warren more tolerable to the financial industry, which could be a serious asset in helping her through a recession. And while Booker seems to be nobody's favorite Dem, it's not like he's despised by moderates or the far left. Add to that he's a good looking guy with a seriously hot girlfriend (would be hottest potential 1st girlfriend since Linda Ronstadt back in the day). I see Inslee more likely as Interior Secretary no matter the nominee. Same with Doug Jones as AG.
