Rick Santorum won big victories in three small contests in the Republican presidential race last Tuesday. In doing so he reshaped the oft-reshaped nomination battle once again. But he has not installed himself as the favorite, and neither he nor Mitt Romney has established himself as the candidate who can do best in the general election.

One constant factor in the 14 contests with exit polls is that Mitt Romney has tended to run best among high-income and high-education voters. His leading opponents -- Newt Gingrich in South Carolina and Georgia, Ron Paul in Iowa, New Hampshire and Virginia, and Rick Santorum everywhere else -- have run best among low-income and low-education voters.

For months, former senator Rick Santorum has been talking about working-class woes and promoting a working-class-friendly economic agenda.

Republican Jane Corwin’s defeat in New York is to Republicans what the election of Scott Brown in Massachusetts was to Democrats: a warning of impending disaster if the party maintains its course. Democrats in 2010 refused to see this, blaming their loss on poor turnout and a bad candidate. Republicans cannot make the same mistake.

Hillary Clinton's recent victory in Ohio may prove that she is more electable than Senator Barack Obama.
