Trouble is, among the voters, maybe 30% are hard right, about the same percentage hard left, and the other 40% are in the middle...and to win an election, a majority of the 40% in the middle must be captured - and they think the hard right and the hard left are both "too extreme".
Anyone who wants to win has to appeal to that group. How would you do it?
Ultimately, he'd have to figure out a way to keep 70% of the electorate from voting.
We've had a few FReepers advocate various extralegal methods of seizing power--military coups, get elected once and suspend subsequent elections, etc.
