Super PACs Wane, Compton's Cowboys, Oscars Diversity

Today we start with a political twofer: Donald Trump is now the established front-runner for the Republican presidential nomination, and Jeb Bush dropped out despite his massive super PAC. Could the influence of super PACs be overblown?

Then, will Trump be able to keep his momentum for Super Tuesday on March 1?

Next, Compton has a long history as an agricultural horse town. We hear from a Compton rodeo rider and a historical expert.

After that, a discussion of the new book West of Eden.

And finally, what can be done to make Hollywood more diverse?
