and Yes, 5 is too many; by at least one.
Here, we have partisanship that causes gridlock; in other industrialized countries, they can't build enough consensus to get a majority to get anything to pass.
Different situations, similar problems.
Oh, and for your info, nobody has become President here w/out Texas and California voting for them; or at least one ofthe two.
After them, NY, FL and OH.
