Any thoughts on the fact in the event of a tied Senate, Orman would have to be known as the guy who (by appearances) single-handedly throws the Senate to the Democrats if he caucuses with them? That would presumably make for an effective attack ad come the 2020 election and might dissuade him now. Then again, it's tempered by the fact it's six years later (meaning voters might care less and also Orman might willingly make that sacrifice in exchange for supporting the party he presumably wants to).
Even if he supports the Democrats now he might switch caucuses at any point before 2020
