It's over. Sen. Hillary Clinton will announce the end of her campaign for the White House on Friday. Los Angeles Mayor Antonio Villaraigosa had endorsed Clinton last year and became one of her national campaign chairs, often traveling the country for her during the Winter. That time spent on the road led to people asking if he was spending too much time away from the city he was elected to lead.

In March, Villaraigosa hinted about supporting Obama if this day would co me -- and here we are: "I spoke with Sen. Clinton yesterday and I said to her, `I've never been prouder to support a presidential candidate,'" Villaraigosa said, according to Rick Orlov of the Daily News. "I also believe that Barack Obama is going to be a great standard-bearer for our party. Yesterday, we crossed a threshold. Americans said it's time for change. They're looking for a leader who can inspire us, and the message is clear -- we all have a lot of work to do to make sure that that change comes to fruition."
