Michigan Roll

The Michigan primary, which proved a headache for the Democratic Party and a hollow victory for Senator Clinton, has been a bonanza for a political consulting firm. State voters do not register by party, so it is hard to reckon the partisan preferences of individuals. Alan Grebner solved the problem by painstakingly examining who voted on which side. The Detroit Free Press reports: "His goal was to identify the party affiliation of voters who participated in the primary and sell the data to political campaigns, which prize such critical information. For about 1.43 million-- or 97% -- of the voters, he was successful."
