I mean, I agree that Khan is the best possible option, but I disagree that pro-market isn't ideological.
Where the free market fans see child slavery and sexual slavery and rejoice (free to make any contract you want to after all), the pro market people believe that if you just put enough guard rails on it, greed will magically turn into a force for good.
Obviously I also have an ideology, but at least I'm honest enough to not pretend that capitalism (or communism/anarchy) are naturally occuring, instead of simply a choice we make.
