President Obama spent much of the weekend in Los Angeles, engaged in fundraising efforts. And as always, Hollywood’s biggest names came out in support.

While in LA, the Commander-in-Chief attended a concert at LA Live and dinner at the Ritz-Carlton, but don’t think for a minute he was on a vacation. The President wasn’t just there to rub elbows with the stars, but to refuel for the final 30 days of his campaign. President Obama lost some momentum after his lukewarm debate performance last week in Denver, CO. He wanted to reassure his biggest supporters (and donors) in Hollywood that he is still the right man for the job.

The President’s LA visit started at the home of Marilyn and Jeffery Katzenberg, the DreamWork’s Animation CEO. While at the Katzenbergs’ house, Obama thanked them for “being tireless and stalwart.” He went on to say the two “have never wavered through good times and bad since my first presidential race, back when a lot of people still couldn’t pronounce my name.” Other guests at the private soiree included former President Bill Clinton and 12 other Democratic donors.

From this intimate affair, President Obama headed downtown to LA Live where he and 6,000 other attendees watched a concert in his honor. The “30 Days to Victory” concert boasted headliners Katy Perry, Jon Bon Jovi, Stevie Wonder, Jennifer Hudson, and Earth, Wind, and Fire. There were also speeches from Los Angeles Mayor Antonio Villaraigosa, as well as San Antonio Mayor Julian Castro and Oscar-winner George Clooney. The president himself took the stage to remind supporters of his first term accomplishments, including the capture of Osama Bin Laden, ending the war in Iraq, and appealing the military’s “Don’t Ask, Don’t Tell” policy. President Obama couldn’t resist taking a few jabs at his Republican opponent, Mitt Romney. As expected, he made reference to Romney’s infamous Big Bird comments in the debate last week. He even joked that “Elmo has made a run for the border” as Romney comes after public television programming.

After the concert, President Obama was ushered across the street to Wolfgang Puck’s WP24 in the Ritz-Carlton. While concert tickets ranged from $44-$250, the price of admission to the dinner was a whopping $25,000 per plate. Attendees included Clooney, legendary film maven Harvey Weinstein, and newly-named Oscar host Seth MacFarlane.

All-in-all, Obama had a very busy visit out to the west coast. The President is clearly backed by Hollywood’s heavy hitters, along with the cast of Sesame Street. Of course, with the final 30 days of the campaign ahead, both Obama and Romney need all the help they can get – Muppet or otherwise.
