It seems to me...
...that must have been influenced by *something* to come to your feelings about the president (unless we are moving to the realm of ESP, I suppose). The constant barrage of nastiness from the right demonstrably has driven down Obama's positive polling and driven up his negatives. The people who have switched opinions, no doubt, would all say it had *nothing* to do with the 24x7 coverage of all that stuff I listed before plus all the lies (think death panels, palling with terrorists, etc.) in the news that I did not mention.
If you say you are not one of those who would be swayed by the propaganda, then I take you at your word.
