Al Gore and John McCain are both great Americans who served our country with honor but made two terrible decisions and miscalculations of character in the name of political expediency. They picked Joe Lieberman and Sarah Palin for their VP nominees.
Once both Joe and Sarah got a taste of the big time, there was no turning back. Their need for attention and relevance and self-importance became all consuming. Joe is seeking to once again (see Dept of Homeland Security and Iraq War, 2002) destroy caucus' chances of electoral sucess in the name of poor policy. Sarah is slowly destroying hers as well (see Hoffman, NY23).
