William Henry Harrison
"Do-nothing" politicians, especially presidents, are never remembered or highly regarded by the masses. The common belief is that a politician must "do something" in order to have effectively served the public. That "something" is always more government, more regulation, more transfer of power from the people to the state.
Harrison, America's shortest serving president, should also be regarded as its greatest as he had only 32 days to loot the American tax payer. We salute you, Bill.
