[EM] 2-party systems are not democracies

[Warren Smith]

I disagree with the claim they are.  Democracy is about
choice by the voters.  2 choices is not enough choice.
Furthermore in the contemporary USA, 98% of the time
incumbents are re-elected if try.  So really it is a 1-choice
system.   Congressmen are more likely to
die in office than to lose an election.  So God obviously
has more say than US voters.  The Soviet politburo
had higher turnover than does the US congress.

2 party system also leads to other undesirable effects...
