Three days after the New Hampshire primary, we are finally getting some polls that reflect the new state of the race — including a poll in Nevada, the next state in the voting sequence, for the first time in a full month! And overall, they’re not showing that any candidate has grabbed a ton of momentum out of Iowa or New Hampshire. That’s probably good news for former Vice President Joe Biden, whose firewall in Southern states appears weakened but still standing. But mostly it’s a recipe for a long, drawn-out nominating contest. In fact, our national primary forecast currently says that the single most likely outcome of the primary season is that no candidate gets a majority of pledged delegates.

Welcome to The Riddler. Every week, I offer up problems related to the things we hold dear around here: math, logic and probability. Two puzzles are presented each week: the Riddler Express for those of you who want something bite-size and the Riddler Classic for those of you in the slow-puzzle movement. Submit a correct answer for either,1 and you may get a shoutout in next week’s column. If you need a hint or have a favorite puzzle collecting dust in your attic, find me on Twitter.

Late last year, graduate students watched as legislators in the House debated giving them a hefty new tax bill: A version of the GOP tax plan proposed to treat tuition waivers as taxable income. Although that plan was later dropped, Congress is once again considering legislation that could affect graduate students’ bottom lines. And the federal government is considering ending some of its student loan forgiveness programs, which could raise the economic barrier to entering certain public service professions and leave social workers, teachers and other people in public-service fields that require graduate degrees paying thousands of dollars more for their education.

Maybe you call it a bubble. Maybe you call it a silo. Maybe you just call it an echo chamber. But whatever metaphorical, narrow and enclosed space you prefer, there’s a good chance you’ve been told that one of the great social problems of our time is Americans getting their political news from biased sources. Conservatives watch Fox News. Liberals watch MSNBC. The news tells us what we already believe and distorts reality around partisan talking points.
