With 85 of 301 precincts reporting, 52,191 voters have cast a ballot in the Republican primary so far. That projects to about 185,000 votes statewide, as compared with about 240,000 votes in the Republican primary in 2008. The drop-off in turnout looks worse for Republicans since a higher fraction of voters - about half this year, compared to 37 percent in 2008 - are independents. That means that turnout among registered Republicans could alone be off by nearly 40 percent from 2008.
