An excerpt from Powerline:
As to which candidate would make a better president, the analysis is not that dissimilar. It’s hard to see Clinton being a good president, at least from my perspective. However, there probably are limits as to how bad she would be. Hillary seems to understand that the world is a dangerous place; that our enemies make it so; and that therefore, at a minimum, we should not be in a rush to accommodate them.
Obama may or may not grasp these basic realities. If he does not, then he will be another Jimmy Carter.
Yet, in contrast to Clinton, one can imagine Obama turning out to be a good president. That’s because there’s some evidence that he’s intellectually open to deviations from orthodox liberalism in ways that Clinton isn’t. In addition, there may be something to his (admittedly self-serving) claim that he’s temperamentally better suited than Clinton to working with his political adversaries. It’s difficult to see how he could be more poorly suited.
In sum, Obama seems to have both a larger upside and a larger downside than Clinton. Being risk averse when it comes to politicians, I’d probably rather see Clinton in the oval office. But fortunately, I don’t have to cast that vote.
