Grist’s Emma Merchant recently crunched the numbers on how frequently climate change has been discussed in the debates of the past five presidential election cycles (2000, 2004, 2008, 2012, and 2016).

She found that, out of 1,500 minutes of presidential and vice-presidential debate, climate change got a paltry 37 minutes of discussion. In 2012, of course, climate change got a whopping zero minutes of debate time.

For Hillary Clinton, it was a classroom in Harvard with scared law school hopefuls trying to keep her from studying justice. For Malala Yousafzai it was a school bus loaded with an armed member of the Taliban, determined to keep her off her schoolyard soapbox. For me — clearly not saving the best for last here — it was a kitchen in the South with a confused freshman Baptist hell-bent on keeping me away from the pulpit.

If there is one constant in this unconventional presidential campaign it is the unpredictability — and importance — of the Catholic vote.

Once a reliably Democratic cohort, Catholics have in recent decades swung back and forth between the two parties. And because they represent more than a fifth of all voters, and are concentrated in key Midwestern swing states, the candidate with the most Catholic support has wound up winning the popular vote.

It may not rank up there with Donald Trump’s “Two Corinthians” coinage or Hillary Clinton’s tortured email explanations, but a phrase that Tim Kaine used in an effort to yoke his Catholicism to the Methodist faith of his Democratic running mate deserves closer scrutiny.

“I’m a Catholic. Hillary is a Methodist,” Kaine said during a Florida rally on July 23 as Clinton introduced him as her vice presidential pick. “Her creed is the same as mine: Do all the good you can.”

Presumptive Democratic presidential nominee Hillary Clinton announced Tim Kaine, the junior Democratic senator from Virginia and former governor of that state, as her vice presidential running mate Friday.

Kaine, a Roman Catholic, will appear with Clinton, a Methodist, at next week’s Democratic National Convention in Philadelphia.

Sanders leaves what was a long and often-contentious race on a high note, having captured nearly 1,900 delegates — "far more," he said, "than almost anyone thought we could win.

White evangelical Christians, a crucial bloc of Republican voters, are backing likely GOP presidential nominee Donald Trump by a wide margin over Hillary Clinton but their support is significantly lower than for previous Republican candidates.

That relatively tepid faith-based endorsement could wind up undermining Trump’s chances for victory in November.

On the eve of her religious denomination’s quadrennial meeting, Hillary Clinton wrote a letter to Jewish agency heads saying she opposes the Boycott, Divestment, and Sanction movement targeting Israel, which the meeting will consider.

“I believe that BDS seeks to punish Israel and dictate how the Israelis and Palestinians should resolve the core issues of their conflict. This is not the path to peace,” Clinton wrote in a letter May 9 to David Sherman, chair of the Israel Action Network, and Susan K. Stern, vice chair of the Jewish Federations of North America.

Hillary Clinton’s presidential campaign is joining with the Democratic Party to sue Arizona after the state’s fiasco of a primary election. Some voters in the primary waited up to five hours to vote.
