I get where you're coming from - but I also have a lot of confidence in people to see through petty and attention-shifting arguments, and to judge character to at least some degree. It all depends on us, our hope, and our faith.
Obama has had to lie, claim executive privilege, and create executive orders whenever the election polls show him losing voters en mass. Mitt Romney has hit a few sad shots, but for the most part has been well aimed in his arguments, and very calculated in his risks - exactly the kind of person we need for president. Mitt Romney is generally honest. People can read that character and appreciate that in their next new president. Breath easy, but help out a little too.
