Editing President of the United States (section)

=== Head of party ===

The president is typically considered to be the head of their political party. Since the entire House of Representatives and at least one-third of the Senate is elected simultaneously with the president, candidates from a political party inevitably have their electoral success intertwined with the performance of the party's presidential candidate. The [[coattail effect]], or lack thereof, will also often impact a party's candidates at state and local levels of government as well. However, there are often tensions between a president and others in the party, with presidents who lose significant support from their party's caucus in Congress generally viewed to be weaker and less effective.
