A protester carries an historic flag during a 'tea party' demonstration against taxes in Lafayette Park across from the White House on April 15, 2009 in Washington, DC. Coast-to-coast demonstrations against Obama's big-spending economic stimulus package are promised for the day that is also the deadline for filing federal income tax returns. The protests are named after the 1773 Boston Tea Party in which disgruntled Americans rebelled against British colonial taxes, an iconic moment in the path to US independence.
