At the ripening age of 80 years old — more than 35 of them spent in Congress — Sen. Richard Lugar, R-Ind., is scrapping for political survival. On Tuesday he faces state Treasurer Richard Mourdock in his party's primary.

German Chancellor Angela Merkel made all the right gestures Monday: the obligatory phone call congratulating French President-elect Francois Hollande. She vowed that the two will "work together well and intensively." And she invited Hollande to Berlin after his inauguration and said she would welcome him "with open arms."

But clearly the French election results mark a setback for Merkel and her goal of solving Europe's economic crisis with financial austerity.

Vladimir Putin is once again the president of Russia.

Putin, who held the job from 2000 to 2008, spent the past four years as prime minister because the Russian Constitution prohibits a third consecutive term.

So his hand-picked successor, Dmitry Medvedev, held the office for the past four years. Now they are switching places, with Putin returning as president and Medvedev tapped to be the prime minister.

As we've reported, Vladimir Putin's return to Russia's presidency was fraught with drama. But a disputed parliamentary election and many unprecedented protests later, Putin took the oath of office for a third time today.

Putin took the oath amid protests. The New York Times reports 300 were detained, following the round up of 400 detained after a surprisingly large anti-Putin demonstration popped up on Sunday.
