Which type of democracy do you prefer? (Presidential or Parliamentary)
Presidential: Powerful Head of State is Head of Government
Examples: US, Mexico, Philippines
Parliamentary: Head of State is ceremonial, Head of Government is elected from the legislative body
Examples: UK, Canada, Australia, Germany, Japan
Semi Presidential: Head of State has considerable power but cabinet (including Head of Government) is elected from the legislative body.
Examples: France
I'll say Presidential because as a citizen I think the U.S. is still okay. There's nothing wrong with the other systems, though.
