It really sucks that an extramarital fling can sink a politician's career in America. In other countries, it's sort of expected that elected officials can be horndogs, just like everyone else. Thus, when someone is running for office or actually holding office, there's are simple solutions for whenever he feels "the urge":
a. Manual stimulation below the belt. In private, dummy.
b. Buying Playboy (as I've mentioned, you can always say you read it for the articles).
c. Inviting your significant other for a night of hot nookie.
Predictably enough, people like David Vitter, Eliot Spitzer, and John Edwards avoid any of these options. In fact, Edwards' little peccadillo may not have been his first (and I wouldn't be surprised if it wasn't). This isn't a matter of scoring partisan points (insert references to Newt Gingrich and John McCain here). In the red and blue camps, you'll hear politicians who blather about morality and are later exposed as hypocrites. So it goes.
I have an idea: Politicians should stop any and all references to morality in their speeches and policies. If you're really so concerned about morality, you have no place in politics.
