all of the above....but more than that for me is the overall ideology. all presidents/leaders do things that we don't agree with or like. sometimes they do the wrong thing for the best of reasons. however, when someone is doing the wrong thing because he believes his country and constitution are fundamentaly flawed, i can't accept or excuse that.
obama was brought up in a Marxist home. his mother, step father, and grandparents taught him this and made sure that the role models he had were the same. he was taught Marxism in college...as are many students, but then taught it in his classes. he attended a black liberation theology church for 20 years. black liberation theology is Marxist.
he believes that government is the solution to all. he does not believe in excellence of country or individual. he does not believe that the private business modle is better than the government "business" model. he does believe in redistribution of wealth through taxation and government programs.
his health care plan is a symptom of his belief that government can run things better than private industry. wars happen...under both parties. however, his actions in Libya are an example of his belief in multi-nationalism and the fact that he feels that our laws don't/shouldn't apply to him. recessions happen...under both parties. we have examples in history of how to handle them, and how not to handle them. he has chosen to follow the examples of how not to fix an economy and in the process has made it much worse, longer, and deeper than it otherwise might have been. what he has done has put us in debt to the point where no one has a clue how we will get out of this mess.
do i think the republican party can fix this? this is not a party issue. this is a conservative vs. liberal issue. if the republicans pick a conservative candidate that will begin to get us back to 1st principles, then yes. if they do not and pick another McCain type....no.
that's my short answer to your question
