OK, I'll admit these predictions are quite as longshots as the ones in Phil's thread, but many would probably dispute them. Anyway:
1-Klobuchar will win by a significantly larger margin than Kerry did
What is a "significantly larger margin"? Could she win by 6-8 points? Yes. Will she win by 10+ points? Highly unlikely, to where I would say no.
Quite possible, it is worth wagering for, though Casey has been polling weaker of late, making the possibility lower.
One would think if the Democrats unite after the primary, it is quite possible. Cardin is still not polling very strong, though, imo.
Schweitzer won in 2000? This is news to me and my executives at Diebold.
In 2004, Schweitzer got 50%. Could Tester get more than Schweitzer did? Probably, but if he got much less, he'd probably lose.
Byrd has been polling in the mid-to upper 50%. That is not the requisite number for a incumbent candidate to break 70%, BRTD, unless you think the polls are wrong.
This could happen. Most definitely.
Except for #5, none of your predictions are really very out-of-the-potential mainstream. I think that opebo has infected your thinking with a white-bread menatliry.
