This is why parliamentary systems suck. No stability. I like to know when our elections are held.
If a majority government takes hold, then it's the standard four years - this stuff only comes up when it's a minority government. If you had three major political parties instead of two, you'd probably have the same problems we do.
No, because our president is elected separately, and thus, there's no need for the Congress to get along in order to govern.
Not much will get done, but we've had deadlock all the time, and we never fail to get a budget passed or anything.
By the way, can anyone veto your laws?
