Today marks the fourth day of the European and American campaign against Gadhafi’s forces in Libya. The U.N.-sanctioned military intervention was originally designed to establish a no-fly zone, but also seems geared to free up the rebels to take on the Libyan leader themselves. We’ll get the latest from reporters on the ground in Tripoli. Here in the U.S., the politics of intervention are heating up. Lawmakers on both sides of the aisle are questioning President Obama about the goals of the mission and top Republicans are ramping up their criticisms. And on Monday, the U.N. warned that Italy is facing a humanitarian crisis following the arrival of some 15,000 Tunisian boat people and fears that more migrants will flee there following coalition air strikes on Libya. Meanwhile, unrest continues in Yemen, Bahrain and now Syria.

Those of you who shop online probably know, you’re supposed to pay sales tax on your purchases. But let’s face it, few consumers do that. Partly, it’s because consumers don’t know how. It’s not as simple as a brick and mortar purchase, where the tax is automatically added. Online buyers are supposed to figure out the tax on their own and send it to the State Board of Equalization. As a result, millions, perhaps billions of dollars are going uncollected. For a cash-strapped state like California, that’s a lot of lost revenue. Now, California Assemblywoman Nancy Skinner is proposing legislation that would require online retailers to tax internet purchases automatically. But some California Republicans aren’t keen on this idea, arguing that collecting these taxes would have disastrous effects. Why are online purchases taxed differently? Should this be changed? Do you intentionally make purchases online to avoid paying sales tax? Are you willing to change your ways to help out the Golden State?

It’s official: former Minnesota Governor Tim Pawlenty pressed toward a White House campaign Monday by formally announcing an exploratory committee with a call for backers to help him “take back our government.” Pawlenty’s announcement is the first in the slowly forming GOP nomination field. What are Pawlenty’s chances to win the nomination and if he makes it that far, in the general election? Can he overcome his “born to be mild” reputation? Will Pawlenty’s move inspire other Republican candidates to finally declare their candidacy?

The steroid scandal that’s been rocking baseball for a decade may claim another victim, and this one’s a biggy! An ex-girlfriend, a personal shopper and an old teammate are all expected to testify in Barry Bonds’ perjury case that started yesterday in San Francisco. The home-run-king is alleged to have lied when he told a grand jury in 2003 that he never “knowingly” used steroids. The witnesses for the prosecution will tell another story though. The ex-girlfriend claims Bonds was so jealous of (fellow steroid user) Mark McGuire’s home run record in 1998 that Bonds started using. A couple years later he bested that record, beating McGuire 70 to 73. Other testimony will focus on Greg Anderson, Bond’s former trainer who is accused of supplying performance enhancing drugs to Bonds and other major league stars. Anderson served time for refusing to testify against Bonds in 2006 and he may be sent back there if he refuses again. But can the prosecution prove that Bond’s didn’t know what he was being shot up with?

Roy Campanella, a.k.a. Campy, was one of the first African-American baseball players to break the color barrier after Jackie Robinson. A mere three years later he became the National League’s Most Valuable Player. He had the respect of legends of the game including Joe DiMaggio who called him “a wizard,” and Ty Cobb who said he was the best catcher in all of baseball. Campanella was on the first Brooklyn Dodgers team to win a World Series and went on to garner two more MVP awards. However, in 1958 Campanella’s career was cut short by a car accident, which left him paralyzed from the neck down. A true testament to his indomitable spirit, Campanella still went on to serve as an inspiration to fellow athletes, fans, the handicapped, and those who never even saw him play. In Neil Lanctot’s new book, CAMPY: The Two Lives of Roy Campanella, the author puts under scrutiny a life not well documented. The exact details concerning Campanella’s accident were unknown, his volatile relationship with Jackie Robinson was often misinterpreted, and his own autobiography was filled with inaccuracies. What really happened to cause Campanella’s injury? How did he live out the remainder of his non-sporting life?
