I've enjoyed the punishment, so I would vote for me again.
Although, even under more cooperative circumstances (the sheer volume of people determined to oppose whatever I came out for was tremendous), a less right-of-center electorate, and no VP crisis, I cannot imagine wanting a second term for a variety of reasons, so I would have weaseled out: I hate campaigning, I have a busy holiday season coming up, plus enough's enough.
Enough is enough. I wanted a term and I got it, so I'll remember to be careful about what I wish for! No, it's been fun. Literally the most frustrating thing is seeing, "Anybody but Labor!!lololol111XX!" No one is going to transcend that, so I have no regrets and have been satisfied with my activity and participation in debates. I do have other things to do in life, you know, so in all my term has been justified.
