Whether you agree with the policies or not, one can agree (if they're rational) that strong leadership can be measured by how much of ones agenda they are able to accomplish.
Leadership doesn't exist in a vacuum. It is all relative. Bush, in 4 years, has accomplished more than Bill Clinton did in 8 years both domestically and internationally.
I would challenge any anti-Bushite here to articulate more significant achievements in Bill Clinton's 8 years in office. Because, like it or not, it's pretty easy to illustrate Bush's accomplishments. And whether youa gree with those accomplishments or not, they are deeds that require strong leadership.
