What's Happening: Clinton and Rubio Are Running

Whatever Hillary Clinton can do, Marco Rubio can do later. A day after Clinton's long-expected presidential campaign launched, Marco Rubio, the freshman Republican senator from Florida, also threw his hat into the ring. Clinton announced her White House bid via video, while on Monday, Rubio told George Stephanopoulos "I believe that I can lead this country."

Their odds: Clinton's seeming inevitability is artificially boosted by polls that show her as a favorite but hampered by many who want her to face a serious challenger. Marco Rubio, as David Graham argues, isn't that popular, but maybe popular enough: "Though he isn't leading in polls, many Republicans say they're willing to consider him and very few rule him out, compared to most of his rivals."

Challenges: Even The Onion insinuates that Hillary Clinton's toughest challenge may be the perception she's a shoo-in. Meanwhile, Rubio may have trouble battling former Florida Governor Jeb Bush, his well-positioned mentor, for both Latino primary votes on the trail and in the invisible primary for big-time donors.

Evening Read

Researchers have been combing over the human genome, hoping to discover the secret to racial-health disparities. What they found is troubling:

For many years, researchers speculated that what they couldn’t explain about disparities must be the fingerprint of some mysterious genetic component. But since they are now able to scan the entire genome, this speculation appears both lazy and wrong. When it comes to why many black people die earlier than white people in the U.S., Kaufman and his colleagues show we've been looking for answers in the wrong places: We shouldn't be looking in the twists of the double helix, but the grinding inequality of the environment.
