You know something? John McCain is the best friend President Obama's got

Because, Obama voters (like me) sometimes feel disappointed in him. We wish he'd just Do the Right Thing; do the things he said he would, and basically be the liberal champion that racist conservatives say he is. We worry that he's strangled his administration with "Washington insiders."

However. Most of the time when we feel this way, we can always depend upon John McCain to come along and remind us that while the Obama administration may sometimes be disappointing, a McCain administration would've been catastrophic.
