TBH the caucus system is horrible
Never mind the fact that Iowa shouldn't go first, the caucus system is idiotic. It excludes a huge portion of the population. Seriously, who has the time to spends hours on a weeknight. Also can't take public transportation. Hell its so complicated its almost like a mini electoral college system that allows someone to win the most raw votes but not the state.
The only reason Iowa keeps it is because it forces candidates to live in Iowa and get to know literally everyone at the state.
Thus the best candidate rarely tends to win. Its the random nobody who camps in Iowa for a year. This is more so in larger fields.
The random candidate who camps in Iowa for a year never wins the nomination, though.
Pete Buttigieg?
He based his whole campaign on winning Iowa and New Hampshire
Probably thinking of John Delaney. He practically did move to Iowa, only to drop out before the caucuses.
