Now we're in the midst of not just advocating for change, not just calling for change - we're doing the grinding, sometimes frustrating work of delivering change - inch by inch, day by day.
Part of the reason that our politics seems so tough right now and facts and science and argument does not seem to be winning the day all the time is because we're hardwired not to always think clearly when we're scared. And the country's scared.
But let me perfectly clear, because I know you'll hear the same old claims that rolling back these tax breaks means a massive tax increase on the American people: if your family earns less than $250,000 a year, you will not see your taxes increased a single dime. I repeat: not one single dime.
Michelle and I don't want anyone telling us who our family's doctor should be - and no one should decide that for you either. Under our proposals, if you like your doctor, you keep your doctor. If you like your current insurance, you keep that insurance. Period, end of story.
