After Iowa

Democratic candidate Hillary Clinton told her supporters after the Iowa caucuses that she's "breathing a big sigh of relief," but she shouldn't rest too easily. And while Ted Cruz won the night on the Republican side, the results will only ratchet up the competition between him and Marco Rubio.

How and why

Two very competitive contests in the Iowa caucuses were decided by very different factors. We look at some key findings from the CBS News Iowa entrance poll to help explain why the various candidates on either side did well, or not so well.

Rubio rising

With the fanfare around the winners of the Iowa caucuses, people are also taking a hard look at the state's third place selection -- Marco Rubio. Political insiders say the fight for the Republican nomination is now a three-man race.

O'Malley out

And then there were two; After failing to gain significant support in the Iowa Democratic caucuses, former Maryland governor Martin O'Malley has decided to suspend his 2016 presidential bid, sources close to the campaign tell CBS News.

Huckabee out

Former Arkansas Governor Mike Huckabee only received about 2 percent of the vote in Iowa on Monday night. In 2008, he won the Iowa caucuses failed to secure the Republican nomination. In December, Huckabee said he would drop his presidential bid unless he placed third or higher in Iowa.

Undying love

Imagine hearing your baby's heartbeat, two-and-a-half years after he died suddenly. For California mom Heather Clark, who decided to donate her son's organs after his death, it became a reality, and as she tells "CBS This Morning," how a personal tragedy turned into something "magical."

Big game evolution

In 1967, Jackie Gleason asked his audience to tune into Super Bowl I on CBS, and the Green Bay Packers beat the Kansas City Chiefs in a game starving for attention. Today, you'd have to be living under a rock not to know the big game is just 5 days away. We've come a long way in five decades.
