1. Libya takes center stage
A violent crackdown has consumed Libya, where Moammar Gadhafi is under pressure to step down in the face of massive protests. Gadhafi has reportedly threatened to sabotage the North African country's oil supply, which would dramatically hurt western interests in the region. Some wonder whether Obama should do more to push the dictator out. View our continuing coverage of the Arab revolts.

2. The battle over unions spreads
Showdowns between politicians and labor unions ramped up this week, spreading from Wisconsin to Indiana, and beyond. Democrats who fled their states to avoid voting on tough anti-union bills are disrespecting democracy, says our Bullpen columnist Ed Morrissey. Yet, according to polls, Americans largely back union rights. One journalist, in an apparent show of solidarity with Wisconsinites, even prank called Gov. Scott Walker (R-Wis.). But are labor unions ultimately doomed? See all of our stories on these union battles.

3. Here come the Oscars!
Sunday evening will bring the much-anticipated 83rd Academy Awards, and with it, an answer, finally, to the question of who will take home Best Picture honors. How will Hollywood deal with the mischievous (and anonymous) street artist Banksy, who is up for Best Documentary? And can James Franco and the possibly unfunny Anne Hathaway score as co-hosts? View our full coverage of the Oscars.

4. Will the government shut down on March 4?
The Obama administration and Congressional Republicans are at odds over a spending plan, and if they can't strike an agreement by the end of next week, key parts of the federal government will close for the foreseeable future. Republicans thus far seem to be sticking to their guns on the major cuts they say Americans want. And while we don't even know what the GOP's long-term plan is, says Bullpen writer Brad DeLong, that doesn't mean Obama's proposal is the solution either. Will either side break this stalemate?

5. Could the economy get even worse?
This month marked the two-year anniversary of Obama's stimulus plan aimed at jump-starting the stalling economy. But economists are worried that the cost of staples like food and fuel will spike in 2011. And investors still may be making ill-advised choices, selling low and buying high.
