Stormy,
I live in a country which has Choice Rank voting (Preference Voting) and the exact opposite happens...
Because people know voting for who you want doesn't spoil your vote, people vote who they want...
There is usually more choice and there are surprises...
West of Ireland voted in the first Muslim in Europe, complete surprise to everyone including the candidate. He was Indian doctor and was running to raise the profile of the needs of the local hospital. People voted him number 1 and then thought were to put there serious contender... Turns out a lot of people did and he became a Irish MP... We said he was an Indian among cowboys...
We have many independent members of parliament, 12% of MPs are independent... 9 parties have seats and there are three main parties.. Ireland run multi-seat districts too..
One Man One Vote is what creates two party systems..
