As clear as mud

John McCain, the "straight talk express" continues to hide his wealth from Americans.  Just about all of his rich lifestyle is due to his wife's beer company holdings.  They file their taxes separately, unlike the Clintons and the Obamas.  

Isn't it relevant to know what exactly McCain's second wife is involved in, since we see her by his side constantly?  I think so.

Cindy McCain: Release the tax returns!
