This is only four elections over two years in one state. Comparing how Libertarians actually vote nationally over time would show if this is atypical. Let's be honest, the Libertarian party, apart from sincere libertarians, is a joke. A flaky party will have flaky voting.
The shifts in both 2020 and 2022 were enough to keep the Republican Senate candidate from winning outright - and just enough to keep people from asking questions...
Libertarian candidates get some “supporter/true believer” votes, plus a tranch of protest votes from people disgusted with the uniparty alternatives. I couldn’t prove it, but my guess is that a given State’s “true believer/supporter” Libertarian vote percentage hovers around a consistent baseline across offices and election years, while the protest votes cast for Libertarian candidates fluctuates in relation to how disgusting the mainstream candidates are, how important the particular race is perceived to be, and the general public mood.
Hazel 2020, 2022 is not fishy. Many LP voters admired the way Kemp had a back bone to stand up to Trump.
As Trump voters we need to face and understand reality.
