In 2000, when her husband's Court accepted George Bush's lawsuit to block the Florida Supreme Court's order that all the votes in the state of Florida be counted - a count done a year later by a newspaper consortium which found that Al Gore actually won more votes in that state - the day after Clarence Thomas blocked the vote count, Virginia Thomas, working at the Heritage Foundation, was sending out emails to vet potential members of the Bush administration. This was weeks before her husband's court illegally decided that Bush had won the election because her husband's court effectively blocked the counting of all the votes in Florida.
