Hello on this Thursday, January 31, 2008. I'm Kristin Volk with a UPI news headline. California governor Arnold Schwarzenegger is expected to announce today that he'll endorse Republican White House hopeful John McCain. The governor's backing could be key to the Arizona senator winning California in next week's Super Tuesday nominating contest. McCain is also set to receive endorsements from Georgia's two Republican senators in the next few days. Georgia will also participate in Super Tuesday. Meanwhile, John McCain and his rival Mitt Romney traded fire in last night's debate in California as they fought for their party's top spot. Romney accused McCain of using dirty tricks and misrepresenting his position on the Iraq war. McCain said the former Massachusetts governor lacked the experience and judgment to be commander in chief. Former Arkansas governor Mike Huckabee complained about the time given to McCain and Romney, saying he didn't come to umpire a ballgame between the two. Voters for former Senator John Edwards are up for grabs. Yesterday, Edwards dropped out of the race for the Democratic presidential nomination. At the time, he didn't endorse either of his rivals, Senators Hillary Clinton and Barack Obama. But one of his aides says he may back one of them in the future. Political analysts say an endorsement from Edwards would have a significant impact on the race. The Senate could debate an economic stimulus package passed by the Senate Finance Committee as early as today. The package would inject nearly $200 billion into the economy over two years to help ward off a recession. It's reportedly similar to a bill passed earlier this week by the House. But there are some differences. The Senate's eligibility caps are double those in the House version. President Bush backs the House version of the bill and has urged the Senate to abandon its efforts to pass a different measure. Thanks for watching today's news update.
