Was Hillary Clinton always unelectable nationally?

[Mr. Morden]

She easily would have been favored over McCain if she'd been the nominee in 2008.  (Which isn't so much a knock against McCain as it is a commentary on the extent to which Bush's unpopularity was inevitably going to sink McCain.)

I don't know to what extent she actually became less electable over time by her own actions, and to what extent she just wasn't suited to the times anymore by 2016.
