He’s got two problems with this plan:
1) Most of the electorate now knows who he really is. If he tries reintroducing himself as the same guy claimed to be when he campaigned in 2007-8, the contrast between who he says he is and who we now know he is will be stark and we will laugh him to scorn.
2) If he claims again to be the Obamessiah and unleashes all his messianic powers to win us over, he stands the chance of healing the blind. The immediate impact of that is that all of the Democrats will start voting against his programs. LOL.
Trust is like a china plate. If you break it, no matter well you glue it back together, you will always be able to see the crack.
Obama “broke the plate”. No matter how much he tries to change his image, the crack will be there.
