Here are all the remaining candidates views on key topics in a nutshell.

I have no issue with Clinton. Actually I was comfortable under the Clinton administration. However, I admit that I was too young and ignorant about politics during his reign to be able to tell whether or not he really did a good job. I won't be upset if she actually becomes president.
But I would prefer someone new for now. If Hilary would really be a better president, then I suppose sacrificing Obama is a better idea. I could imagine that you can't expect any good results right away from any candidate who is going to inherit what Bush left behind.
1. Obama --> Cleans up some of Bush's mess. Hopefully end up being a decent president.
2. Hilary/Someone else ---> Has less issues to inherit after Obama, and hopefully start off well on next election.
