In no particular order:
Poor Judgement - his longstanding relationship with the TERRORIST Bill Ayres (that he's DESPERATELY TRYING TO HIDE AND COVER UP) Here's a link: http://www.powerlineblog.com/archives2/print/021285.php
Poor Judgement - he's trying to silence his critics who seek to expose his relationship - see this link: http://www.powerlineblog.com/archives2/2008/08/021325.php
Poor Judgement - his 20yr relationship with a RACIST and HATE-FILLED church, his pastor - Rev. Jeremiah "KKK" Wright and sidekick priest Father Phlager.
Poor Judgement - his relationship with convicted felon and Illinois slumlord Tony Rezco.
He's just another prototypical corrupt Chicago polititian: see this little synopsis: http://www.americanthinker.com/2008/08/obamas_bag_of_tricks.html
Poor Judgement - He was 100% wrong on his signature issue and claim to fame - his opposition to the Iraq War; and his assertion that we couldn't win.
Poor Judgement - although he heads a Subcommitte of the U.S. Senate, the Senate Subcommittee on European Affairs (which includes oversight of Afghanistan), he has never bothered to hold a meeting. That's "LEADERSHIP"??? huh? See this link: http://www.powerlineblog.com/archives2/2008/08/021164.php
Poor Judgement - his plan to impose a WINDFALL profits tax on Big Oil Companies and REDISTRIBUTE the proceeds as $1000 checks to every American family. Newsflash to Obama - we are NOT a socialist country.
Poor Judgement - his allegiance to Socialist Saul Alinski.
Poor Judgement - his work as a "community organizer" for an organization that's been convicted of VOTER FRAUD: ACORN
Poor Judgement - he supports INFANTACIDE
He doesn't represent America: He and his runningmate Sen. Joe Biden have been identified as TWO of the THREE most liberal Senators in the U.S. Senate. These are two EXTREMISTS - and don't represent the majority of America in the least.
Lack of Accomplishments - the guy has never done ANYTHING. Not one piece of important legislation bears his name. His supporters cannot name a single milestone accomplishment - much less ANY that demonstrate he's qualified to be President of the United States.
The guy is a joke.
And to be honest - so is the party who allowed themselves to be hijacked and bamboozled by a bunch of extremists into nominating The Joke.
