Why?

If there is no media bias then...
Why is every movie about a president picture the Republican as

• stupid
• greedy
• insensitive
• brutish
• immoral (or at least amoral)
  
• uncaring
  
• for 'evil corporate concerns'
  

while the Democrat is

• loving
• kind
• smart
• whity
• moral,
  
• cares for the poor
  
• for the 'working man'

Don't belive me? American President. Dave. Swing vote, need I go on? West Wing, MASH, etc.
