This Morning from CBS News, March 8, 2016
Horse trading
What happens if no Republican has enough delegates to win the nomination outright? If the four remaining candidates, Donald Trump, Ted Cruz, Marco Rubio and John Kasich, stay in the race and continue to split delegates, it's possible Americans will see something that hasn't happened in Republican politics since 1948; a contested convention. So how does that work?
Clinton kickback
President Obama's support for tighter gun control rules has helped spur firearms sales. Now, gun dealers say the prospect of a Hillary Clinton victory in the 2016 presidential election is helping to keep sales booming, especially as the Democratic front-runner calls for tighter firearms checks.
2 years gone
Malaysia Airlines Flight 370 veered off course and disappeared, taking all 240 people on board with it, two years ago today. The search in the Indian Ocean continues, but so far only one confirmed piece of the plane has been found. Families of the missing are adamant the hunt must go on, but are we any closer?
Getting grounded
Astronaut Scott Kelly says it was easier to spend nearly a year in space than to get used to gravity again. He lived on the International Space Station for 340 days. As NASA runs tests on him to learn how extended space travel impacts the human body, Kelly tells CBS News about readjusting to life on Earth.
Diplo-matic
It could take years to lift the trade embargo in place since the 1960s, but artists have led the way in forging a new era in U.S.-Cuba relations. DJ Diplo and electronic music group Major Lazer were the first major American artists to perform in Cuba since the U.S. eased relations, and Charlie Rose was along for the party.
"Writing My Wrongs"
Shaka Senghor is a college lecturer and MIT consultant. But his success came after a deadly mistake; he shot and killed another man 30 years ago. He's still filled with regret, but says his life today is proof that even our worst deeds don't define us. He shares his transformation in a new book called "Writing My Wrongs."
