How confident are Iowa Democrats in their choices, now two weeks out from the caucuses?

The response Renee Kleinpeter gave NPR when asked which candidates she's narrowed her choice down to could sum it up: four seconds of laughter.

"I'll go with anybody who could beat [President] Trump," she said after laughing. "I wish somebody could tell me."

Leading Democratic presidential candidates on Tuesday blasted President Trump's decision to kill Iranian Maj. Gen. Qassem Soleimani, casting it as a dangerous escalation in a volatile region.

A three-month window that began with a heart attack ended as Vermont Sen. Bernie Sanders' strongest fundraising quarter yet.

Sanders' campaign announced it raised $34.5 million in October, November and December — nearly $10 million more than he had raised in the previous quarter. According to the campaign, $18 million came in from 900,000 individual donations in December alone, as Sanders drew larger and larger crowds to rallies in early voting states such as Iowa and New Hampshire.

California Sen. Kamala Harris is dropping out of the presidential race, citing a lack of funds. She informed her campaign staff of the decision on a conference call and later sent an email to supporters, in which she wrote "my campaign for president simply doesn't have the financial resources we need to continue."

Former Massachusetts Gov. Deval Patrick is making a last-minute entry into the crowded Democratic presidential primary.

A source with direct knowledge of his decision tells NPR that Patrick has been making calls to Massachusetts and national elected officials and supporters to brief them on his plans and that he plans to formally enter the race as soon as Wednesday night.

Patrick's decision is about as last minute as it gets for a candidate who still wants to compete in the key early primary states: New Hampshire's filing deadline is Friday.

Former New York Mayor Michael Bloomberg is weighing a late entrance into the Democratic presidential primary, reversing course from this spring, when he said publicly that he would not run.

Massachusetts Sen. Elizabeth Warren has been calling for President Trump's impeachment since the spring. California Sen. Kamala Harris wasn't too far behind her. New Jersey Sen. Cory Booker's been pushing for it for months.

In fact, all six U.S. senators still running for president are backing the House's impeachment inquiry.

But now that the lawmakers may be getting what they want, many political operatives see it as a train wreck for their presidential campaigns.
