It's typical to fear what we don't know. I would encourage people to learn more about the man instead of being spoon-fed crap like Rev. Wright or Ayers or his Muslim father - people get those tidbits and then weave together their own stories about the man that are based on hunches and assumptions.
However, if you fear Obama b/c of his policies, you also probably feared Clinton, and perhaps that fear was unwarranted.
Also, you must be confounded by the number of educated voters who will vote for Obama in November - what are they thinking???
