Minutes after President Barack Obama endorsed gay marriage on May 9, Colorado's Democratic governor choked back tears as he ordered state lawmakers to reconsider a civil-unions measure defeated the day before by Republicans.

BELGRADE (Reuters) - Pro-Western Boris Tadic will bid on Sunday for another five years as Serbia's president and the right to lead the nation into EU membership talks, challenged by rightist Tomislav Nikolic who has threatened to contest the result in the streets. Tadic is tipped to defeat Nikolic in the presidential election for the third time since 2004 as Serbia slowly sheds the legacy of a decade of war and isolation under late strongman Slobodan Milosevic. A Tadic victory would keep power firmly in the hands of his Democratic Party. ...

"I have a brain, I won't vote for the PRI," one banner read. ...
