"That's not John McCain, sweetie, that's Joe Biden, Barack Obama's running mate."
Today his buddy E came over. E excitedly exclaimed, "Look! There's Hillary Clinton with Obama!!"
His older brother M, aged 6, heard him and said, "That's not Hillary Clinton. That's George Bush."
Clearly the Obama-Biden campaign needs to increase "brand recognition" for Joe Biden to the under 7 demographic.
