Tough call between Heller, Flake, and Heitkamp. All of them played at being moderates but weren’t - so I guess they’re all kind of equally mediocre.
Heitkamp wasn’t a moderate to you?
In what universe were any of them moderates. Heitkamp votes against the tax bill, healthcare repeal, and (effectively) against both SCOTUS nominees. She never made any attempt to advance bipartisan legislation of any kind and made no attempt to engage Rs on spending bills. She is no more of a real moderate than Heller was and Collins is. Ultimately they’re all fake moderates with the possible exception of Manchin and Murkowski.
So to be moderate, you need to support far right wing legislation on taxes, healthcare, and two far right wing justices?
If that's your definition of moderate, then of course she's not a moderate. But the term would be meaningless. Being a moderate doesn't have to mean you support far right wing proposals.
