evidence: Although this book discusses this asymmetry in politics, it does not let Democrats off the hook. It's not like Democrats never lie, and I don't recall the exact percentage, but Democrats are still responsible for a huge share of lying. We shouldn't look upon this as just a Republican problem. [...] on why politicians lie [...] Can we get politicians to reduce their lying? I'm hopeful for this reason: politicians lie because it's a calculation. They think that it pays off. They think that they get something out of it. So, if we can adjust that incentive, I think we can reduce lying.
