Former Republican Rhode Island Senator Lincoln Chafee on Tuesday evening called George W. Bush the worst president in U.S. history and the occupation of Iraq the worst foreign tragedy in U.S. history. Chafee said Bush deserved to be impeached.

Chafee served in the U.S. Senate from 1999 to 2006 and credits his defeat in 2006 - as do most analysts - to his membership in the party of Bush and Cheney. In 2003 Chafee was the only Republican senator to vote against authorization to attack Iraq. Chafee and John McCain had been the only two Republican senators to vote against the first round of Bush tax cuts.

While Chafee is supporting Barack Obama for president, he said on Tuesday that the Democrats as well as the Republicans have moved too far to the right. Without any apparent bitterness, Chafee remarked that while voters got a new Senate and House in 2006, they didn't get any changes in policies out of it.

Chafee made his remarks on a radio show I hosted, the audio of which can be found at
