Fireworks at the Democratic debate last night.. the final Dem debate before the Iowa Caucuses and the New Hampshire primary with Hillary Clinton and Bernie Sanders all tied up in polls of the two early states. They fought over who would be tougher on gun control and Wall Street. Hillary attacked Bernie Sanders plan on healthcare (essentially arguing he would destroy Obamacare to create a new national health plan from scratch).

New NBC News/WSJ polling shows Hillary Clinton has expanded her lead nationally. She has 25 points on Bernie Sanders.

The Washington Post reporters Anne Gearan Philip Rucker write today, “Democratic front-runner Hillary Clinton aggressively prosecuted Sen. Bernie Sanders on issues from gun control to health care and fealty to President Obama at a presidential debate Sunday as she sought to puncture Sanders's insurgent appeal and regain her footing after a difficult stretch. Clinton put Sanders on the defensive through much of the two-hour debate, but a hoarse-voiced Sanders got in numerous digs. He accused Clinton of being too cozy with Wall Street and beholden to the financial industry. He noted that Clinton has accepted millions in campaign donations and hundreds of thousands in speaking fees from the financial sector.”

Also in the Washington Post, Dan Balz writes, “Two weeks before Iowans gather for their caucuses, Hillary Clinton sought to blunt the momentum behind Bernie Sanders's grass-roots insurgency. In response, Sanders raised the volume and the stakes, appealing to Democrats to support his call for a political revolution.”

On the GOP side, Ed O’Keefe and Sean Sullivan write in the Washington Post, “Rubio, Christie, former Florida governor Jeb Bush and Ohio Gov. John Kasich are locked in heated competition to emerge as the alternative to the insurgent GOP front-runners, Donald Trump and Sen. Ted Cruz of Texas. On the trail and the airwaves, the four-way rivalry has become a twisted web of nasty one-on-one feuds that threatens to do lasting damage to the stability of the party's establishment wing.”

Political and business leaders (and a lot of rich people) will be in Davos, Switzerland for the World Economic Forum.

It’s the 30th anniversary of the federal holiday that honors the legacy of Martin Luther King Jr. There will be marches and services in honor of the slain civil rights leader across the country today.

Three Americans were kidnapped from a translator’s house in Baghdad this weekend. Iraqi security forces are going house to house to find them.

One American is among the 28 killed in an attack on a luxury hotel in the capital of Burkino Faso. An Al Qaeda branch is thought to be to blame.  

Three Americans finally released by Iran over the weekend are being medically evaluated now in Germany. One other hostage is already home in Massachusetts. Another has chosen to remain in Iran.

In exchange for the Americans, the U.S. released pardoned or dropped charges against seven Iranians serving time for sanctions violations.

The United States also unfroze Iranian assets and lifted sanctions as part of the big Iran nuclear deal. Iran has shipped much of its nuclear material to Russia, and has dismantled some equipment and destroyed a reactor.

Oil has fallen below $29/barrel.. the lowest in 12 years. Eric Bolling on that scary number for the energy sector.
