I agree that the U.S. needs a strong 2-party system.
No, no and furthermore. No.
The US, like the UK, needs a strong
voting system.
First of all, I think my statement (I was one of the people who said the U.S. the 'needs a strong 2-party system') may have either been misunderstood or taken out of context.
When I talk about the need for a '2 party system', I was referring to the problem if/when one of the major political parties collapses. (For example, if demographic shifts in the future make it almost impossible for the Republicans to gain power, on account of their racism.) That particular situation is not desirable since its possible for one party to become complacent.
The two party system is fundamentally broken and the FPTP voting system that we use gives us two party politics, and that shortchanges us a lot.
You are right in that the political system in the U.S. is "broken" in several ways. However, that isn't necessarily due to 2 party politics. Its more due to a lack of integrity and racism on the part of one of the parties.
Voting is like a false dichotomy. Vote red or vote blue. Don't like either candidate? tough.
If instead people could vote red, blue, purple, yellow, orange or green then our governments would more accurately represent the electorate, filibustering and rabid partisanship and gerrymandering is much harder to accomplish.
There are advantages and disadvantages to 2 party and 3+ party politics.
Yes, multiple parties would mean that you could vote for a representative that best reflects your preferences. But, it also means things like vote-splitting and coalitions (where your preferred party may enter into a coalition that you might not agree with, or where minor parties receive more influence than the popular vote suggests they deserve.) At least with a 2-party system, you know that the your vote is your vote. Vote splitting is minimal.
As for the other issues...
- Filibustering is not necessarily a bad thing... it is a way that forces a certain amount of bipartisanship and compromise
- Gerrymandering is a problem, but I don't think its strictly due to the 2 party system. (You could easily get gerrymandering under a multi-party system if a coalition decides to team up.)
If you look at the US and the UK there are presently no stand out candidates from any party that you think "hey they'd make a great President/PM" I think that's also a symptom of 2 party politics.
Canada has a 4 party system (3 major federal, 1 regional) that doesn't really have any stand-out candidate either.
If a given party had to beat out several other parties that all had reasonable chances of being elected then you would need to focus more on positive campaigning to point out what you would do to help, rather than negative campaigning and belittling the other party, as there is now more than one main rival party.
Canada has 4 parties. Trust me... there is more than a little negative campaigning.
And it should be pointed out that negative campaign ads are not totally evil. They can force politicians to clarify their policies.
