New Jersey Governor Chris Christie expected to become the latest Republican to throw his hat in the ring for 2016. He’ll make the announcement today at 11am from his hometown of Livingston, New Jersey.

The Governor faces an uphill climb for the nomination with low poll numbers, and a fundraising deficit. The Washington Post reporter Robert Costa writes of Christie today, “his status as the establishment favorite for the GOP nomination has vanished. Dogged by scandals and plummeting popularity in his home state, Christie has seen many of the mega-donors who once toasted him drift toward his rivals, including former Florida governor Jeb Bush.”

But don’t write him off. Maggie Haberman in the New York Times today explains why, “More than any other candidate, Mr. Christie is poised to run a race that sells his personality -- brash, challenging and often combative -- as his main asset. He has become a maestro of the town hall meeting, standing in a suit taking questions from New Jersey residents around the state until none remain, leaving some people enraged but many more laughing, weeping or hoping he would come over and clasp their hand.”

Hillary Clinton facing a very different political landscape that that of 2008. The New York Times writing today, “Hillary Rodham Clinton will seek out donors to her presidential campaign from a Democratic fund-raising landscape vastly altered since her first presidential bid and far more ideologically aligned with the party's liberal activists.”

Hillary also getting renewed attention today for her role as Secretary of State during the Benghazi terror attacks of 2012 that left four Americans dead. Missing emails continue to haunt the campaign, and there’s new allegations over the initial claims that the attack was inspired by an anti-Islam video.

We’ll be paying close attention again today to world markets and the U.S. stock market. The Dow lost 350 points yesterday after steep declines around the world on a trifecta of bad news. Puerto Rico and Greece are close to defaulting on their debts, and China’s stock market has been plummeting. Today is the deadline for Greece to make a $1.5 billion dollar payment that it will not make. Puerto Rico can’t pay back some $72 billion in public debt. Asian stocks rebounded sharply today. Stocks in Europe are down again today, but not too terribly.

Today was supposed to be the final deadline day for a deal to limit Iran’s nuclear program, but it’s so far elusive. Both sides say they need more time. The Congress and many analysts are skeptical.

A major fire burning in Washington State has destroyed at least 24 buildings and forced the evacuation of 1000. There’s another big fire in Southern California. Alaska has some 600 wildfires.
