Schwarzenegger endorses McCain

Another day, another big endorsement for John McCain as he tries to consolidate his support toward the Republican nomination.

McCain, who won the blessing Wednesday of Rudy Giuliani, was endorsed this afternoon by Arnold Schwarzenegger, the governor of California, the biggest prize on Super Tuesday with 173 delegates.

"I'm interested in a great future," Schwarzenegger said, flanked by McCain and Giuliani at a Los Angeles solar energy company. "Senator McCain has proven over and over again he can reach across the aisle to get things done....He's a great American hero and an extraordinary leader."

Schwarzenegger praised McCain's credentials on national security, his crusade against wasteful spending, and his advocacy of action on climate change. "This is the future. The future is clean technology," the governor said.

Both Giuliani and Schwarzenegger, however, appeal to more moderate and liberal Republicans. Many conservatives, whom Mitt Romney is trying to court, are still skeptical of McCain, over his past positions on taxes, campaign finance reform, and immigration.
