Go vote! Californians sure are. New numbers reported by the Associated Press show an all-time high of 18.2 million registered voters in California, but a 30 percent decline in the number of registered Republicans. Officials credit a new online registration system ? which attracts young, Democratic-leaning voters ? for the boost. The decrease in GOP voters is bad news for Romney in an already presumed blue state. The Secretary of State said Republicans now make up 29.3 percent of the state?s electorate? down from 31.4 percent in 2008.
