Under the Presidential system of government, the legislature and the executive are elected separately to a fixed term. This means that voters elect the members of the legislative branch (such as the House of Representatives and the Senate) separately from the executive branch (the President and Vice President). They are both elected to a fixed term, meaning that they serve for a specific number of years before facing re-election. This is different from a parliamentary system where the executive branch is formed by the majority party in the legislative branch and serves at the pleasure of the legislature.
