Really you don’t need to read more than one chart:
If you vote for anyone other than Harris, you’re voting for Trump:
There are lots of competitors in US elections, but most are eliminated during the primaries.
When you have more than two candidates in the final round, the winner may not represent the will of the people. You can end up with a majority preferring A to B, a majority preferring B to C, and a majority preferring C to A. No matter who wins, the majority can identify a preferable candidate.
In fact, Kenneth Arrow mathematically proved that multiparty elections will always produce paradoxical results like that. That’s why the winners of multiparty elections are often decided by elite kingmakers, eg Macron.
I see the issue with a president. But most legislation comes out of the Senate. Having more then two parties represented there forces compromises. And the wishes of more people have to be considered the get the required majority.
And if the congress is more diverse, the president looses some powers, as he can not rely on having the majority at least for two years of his presidency. He also would have to compromise all the time.
Just admit it, your system is broken.
First of all, in a presidential democracy the president keeps their powers regardless of the composition of Congress (not just the Senate).
It’s true that in order to pass legislation, the President has to cooperate with Congress. But I’m not sure why you think that a more diverse Congress would “force” anyone to compromise. What actually happens is that nothing gets done.
In fact, this is why the purest multiparty democracies, like Italy and Israel, constantly fail. Multiple parties are “forced” to compromise. They can’t or won’t, blaming their opponents. The government is paralyzed and falls. New elections are held. The composition of the legislature changes (or not). Multiple parties are “forced” to compromise. They can’t or won’t, blaming their opponents. The government is paralyzed and falls. New elections are held. Repeat ad infinitum.
I am living in a multi party country. I am experiencing the hurdles and the benefits of it every single day. Coalitions have to be formed to get the majority, smaller parties getting influence because of it.
We are getting stuff like increased minimum wage, social benefits, legalizing cannabis, and more. And not because the senior partner in the coalition wants it. Because of the junior partners. They are required to form a majority, so they can state their terms also.
And yes, some countries with more then two parties in the parliament are failing. What about the US?
Got some universal Healthcare yet? A livable minimum wage for everyone including waiters?
Effective countermeasures to climate change?
No? See, also failing. And that lies in the nature of countries. Sometimes they fail.
