The truth is that Mitt Romney -- as we learned during the debates -- would not have operated the drone-killing program any different from Barack Obama. The flying death robots would be used a lot, and some bad guys would die and some innocent women and children would die -- just as happens today. And another truth is this: This is exactly what some civil libertarians warned -- but not loud enough -- when presidential powers were unconstitutionally expanded under George W. Bush, that a Democratic president would not give these powers back. And the biggest truth is this: That the corrupting power of drone killings -- to make things happen with the push of a button rather than the messy process of dealing with judges and Congress and a free press asking questions -- is all but absolute. Look how it has sucked in President Obama -- lock, stock, and barrel.
