Some question if they will? There's been rumors that Mongiardo's refused to endorse Conway. At the very least, he hasn't done it yet.
Philosophically I think Mongiardo might have more in common with an anti-establishment, anti-corporatist Constitutionalist then Conway.
This race was about the Establishment vs the anti-Establishment. The establishment won the Democrat primary. The anti-establishment won the Republican. Their are freedom wings and their are fascist wings of both parties. It’s not about Democrat vs Republican. It’s about the people vs the political class. Like Rand, Mongiardo represented the people of his respective party. I wish him well.
