Well, a state with a large electorate is going to show more superficiality because campaigns have to be mass media.
Iowa, a small caucus state, expects to see and hear a candidate face to face. Any candidate complaining about debate standards can work Iowa, New Hampshire and/or South Carolina county by county and build a base (relatively cheaply) the MSM can’t ignore. That’s why it’s a good idea for small states to go early, but the candidate can’t be lazy or believe himself entitled.
Make it a federal law.....have all primaries for POTUS on the same day. You won’t have leftist gangs of scum going from state to state to vote multiple times and start trouble at the polls.
