@mitch In many ways it's simpler than the American variety - the Commons wields pretty much all the power at the federal level (as opposed to having a president from one party while the other controls Congress) and it all gets elected at the same time (as opposed to having only a third of the American senators stand for election in any presidential cycle). There aren't even any term limits to worry about - as long as the voters are happy enough with you to keep you around, they're allowed to do that.
