The Iowa caucus is really not representative of anything. That’s a fraudulent election if there ever was one. As the voting process there is not anonymous, the Trumpist cult could use their usual intimidation tactics, which we saw in the 2020 election and we have seen against members of the congress, who have had their family members threatened. The turn-out in Iowa was record low, probably for a reason.
New Hampshire is gonna be more interesting, though it is also unusual for different reasons.
