The first half of the above comment is one of the good points I said you made in your previous post. Obama may have to save his most radical changes for the second term if he wants re-election, you are likely correct.
As to the second part of your comment, there are a number of changes he can make in the first four years which we may not be able to undo easily or at all, which include but are not limited to, appointments to the supreme court.
Our opposition to him should begin now and so should our organization and strategy, and perhaps we can diminish the harm he will be able to do those first four years and/or cause him to be such a disaster, he'll be tossed out of office after the first term. Further, I'm unwilling to give such a person any credit what so ever, unless at the time, we either deem it in the interest of the country or ourselves.
However, I don't think we'll have to worry about giving him credit, particularly if he enacts the socialist policies, his past so indicates. What's more, we'll have to work ardently to be certain Obama gets the blame, for his failures, and not President Bush or any other innocent party.
We don’t have four years - We need good republicans in place for the election in 2010. Hopefully he won’t have any supreme court appointments to make before then.
