Other than Rick Weiland (kinda) and Amanda Curtis all of them were really conservative wehateourownparty wearerepublicanslite Democrats.
I don't know if any of them should have been saved, really.
Braley and Udall - conservative? You have peculiar set of political views.... Both are
at least - moderate liberals. And both ran in not too liberal states, and lost not because they were insufficiently liberal, but, may be - because they were
too liberal. Essentially the same - with Begich and Hagan. And Curtis was so much more liberal then Montana is, that she had zero chances from first day of campaign.
