I don't yet know how I'm voting in the upcoming presidential election, though I do know it will be a matter of the least objectionable candidate rather than some ringing endorsement. Frankly, I find them all objectionable; the question is, Who will do the least harm? So I'm not endorsing any candidate at this point, but as I've said before, Barack Obama scares me because he's so charismatic he might very well succeed in implementing some very dangerous policies.
Tim at Random Observations once again has a thoughtful post, this time on why Obama scares him. Check it out.
