I heard a great analogy about this a few weeks ago...in a nutshell...
Running for President is like buying a house. If you end up buying the house - with all its imperfections - it’s now your house. Blame the previous owner all you want for said imperfections, you bought it nonetheless. Those imperfections are now your responsibility, and they’re your responsibility to fix.
If after several years of owning said house and those imperfections still exist - because you haven’t tried to improve upon them - whose fault is that?
Not the previous owner.
Great analogy
