The GOP needs to figure out a way to become more appealing to new constituencies.

Three explanations dominate speculation about what Obama is up to. The first is that he's trying to lay the groundwork for his successor, presumptive nominee Hillary Clinton. The second is that he's trying to pad his legacy. The third is that he's trying to 'troll' or bait the GOP into debating his agenda rather than pursuing its own.

Those who say they dislike dogma, or 'certainty', tend to be liars, hypocrites, or simply wrong. What they really dislike is the dogma of those they disagree with.

Such things are only possible when you're open to new ideas.

There's nothing within science per se that says medical researchers must not experiment on human subjects; it is the imposition of ethical dogma that constrains the scientist.

I have a simple answer to any American patriot who claims that there is no conflict between his love of country and his desire to hitch our fate to the United Nations: “You're mistaken.” And, therefore, I'm thinking of adding this corollary to my General Rule of patriotism: The more intellectually consistent and pro-U.N. you are, the less patriotic you are likely to be.
