I know Oabam was not in office during the Carter administration, however, if you look at them both, you will see that they would agree to most of the same policies and would vote pretty much the same way as one another.
so therefor, you can't dispute that Obama is a Carter Clone.
Actually, I think you both have this wrong.
Carter was a horrible president who happened to be Democratic.
Bush is even a worse president who happens to be Republican.
Since Bush's incompetence exceeds even the uselessness of Carter, it is fair to refer to Bush as the Republican Carter.
Now, it may be true that if you supplied Obama with a time machine, he would use it to go back in time to support Carter. But since time machines don't exist, that remains a theory and only a theory.
But Obama requires no time machine to make his feelings known about the Republican Carter. The Republican Carter is still in power. So while we'll never know how much support Obama would have given the Democrat Carter, we can know with certainty he does not support the Republican Carter.
But what about McCain? We can theorize that McCain would have given little support to the Democrat Carter. But without that time machine we can never know for absolute certain.
But we know McCain is quite supportive of the Republican Carter. Thus it is fair to assume that if he attains the Presidency, McCain will become the new Republican Carter. Or if you want to shorten it, McCain will be the new Carter.
So if you liked Carter, make sure to vote for McCain.
