There are not enough people out talking about the President positively.
While the President leads his potential adversaries in almost every state, his support is soft. He is seen as honest, sincere, just, and friendly but gets mediocre or relatively poor ratings being competent strong, intelligent, and a forceful leader.
I think he could have made most of the trips and gone to most of the fund-raisers if he would have avoided the partisan rhetoric and talked to the country as President in each of these appearances rather than to the narrow partisan audiences.
People feel that decisions about their jobs, the way their children are educated, how their church functions, and products they buy are made by someone and some place so distant that they can’t find anybody to talk to that has any influence over them.
