“I’m worried about unaffiliated in CO - different breed there”
I’m not. Lots of those CO UAs are like me: former Pubs who could no longer stomach the RINO/Paul Ryan stench. There’s also others who’ve fled a Democrat party that’s now more representative of Karl Marx than Jack Kennedy.
Plus I think it’s a reasonable assumption that there are fewer knee-jerk voters amongst CO UAs than R’s or D’s, and the CO UAs instead might actually pay a bit closer attention to what’s actually going on in trying to make an informed decision. Certainly I put more hope in the CO UAs than the CO D’s.
Likewise.
Because of the primary situation here (more specifically, the lack-of-primary situation), there is little reason to affiliate. And if there is a primary of interest, one can temporarily affiliate in less time than it takes to fill out the ballot. Just plan ahead and affiliate 30 days in advance.
