Gov. Arnold Schwarzenegger is warning the state's Republican party to move toward the political center or risk losing voter support. Schwarzenegger is speaking Friday night at a state party convention in Indian Wells near Palm Springs. According to excerpts released in advance of his speech, Schwarzenegger says the party has lost the political middle and "will not regain true political power in California" until the GOP gets it back. He argues the party must tackle issues with broad public appeal, like climate change and building highways, railroads and tunnels.
