If I could say only one thing to an undecided voter, this is what I would say. The next President is inheriting a lot of challenges, existing ones and ones yet to unfold. We need a President with experience and backbone, and McCain's record shows he clearly has both. I have yet to see a single compelling example of Obama showing either.
Thanks to Blogs4McCain for the video link. (Be sure to see Ed Morrissey's comments at Hot Air as well).
