It's an interesting campaign that only a somewhat political novice can pull off.
Yes.
He can run it this specific way only once.
But you still have to be good at campaigning to pull it off (I mean even be competitive. Winning will still be hard.)
If he wins, I think he will have a challenging time staying out of political trouble in his solidly Red State.
If he wins, he would have trouble no matter whether his state was red or blue.
Independent is a hard line to walk given the system and when so much of his support is "screw the incumbent" that's a hard coalition to keep together.
He can be a gadfly for six years à la Kyrsten Sinema. Now his situation is different than Sinema. Sinema was attacked from the left and right. She found herself without a base.
He is in a
much different position than Sinema and is running a very different campaign.
She wasn't much of a gadfly, either, which is one of the reasons she lost her base.
A gadfly would have a much more consistent political position than she did.
If Osborn doesn't fall solidly into the Dem caucus, he could possibly find long-term success offering Nebraskans something beyond hardcore conservatives. Of course, the Nebraska Republicans could wise up and put up a more flexible candidate to challenge him in 2030 in the event he wins.
How he caucuses will be a big deal and I stand by my prediction that it will depend on who is in power and what the numbers are.
He has basically said he would caucus with the majority (although he's hedged it in various ways).
The fact is that unless the numbers are very close, he will pretty much only be along for the ride in many ways and have very limited things he can do.
Most predictions seem to have it at 51-49 or 52-48 for the GOP.
But those include Fischer keeping it.
If it ends up 50-49, I expect him to caucus with whoever controls the presidency. (Since that will allow the VP to tie break and he can demand a lot if the Dems have the white house and siding with the Dems gets him nothing if the GOP does.)
If it ends up 51-48 GOP, I kind of figure he officially doesn't caucus with anyone since he is ignorable except when there is a chance a GOP senator might defect.
He's talked about reaching out to Collins and Murkowski and trying to make some sort of "Independent" bloc that would hold the balance of power, but I find that extremely unlikely.
(Maybe on a couple of specific votes, but not as an actual caucus bloc of their own.)
The Manchin thing is so unique that I don't think we will ever see this type of situation anytime soon. Popular moderate Governor sees his state solidly turn to the other party. I think it's conventional wisdom that Manchin would have trouble getting re-elected this year if he ran.
It is.
The Manchin comparisons were primarily about him being the right edge of the Democratic caucus in an extremely tight situation and therefore being able to wield a lot of power to get his preferences on things.
That only happens in the 50-50 situation with a Harris win, above.
