Anyone who has any doubt -- I suggest you read chapter 4 of "Sellout" -- by David P. Schippers, Chief Investigative Counsel for the Clinton Impeachment.

Anyone who thinks the liberals have not gotten better at voter fraud (including overseas military) -- I've got a great bridge for sale -- great location, great price.
