Republican Governor Scott Walker won the election in Wisconsin yesterday, making him the first governor in U.S. history to survive a recall election. Political pundits are having a field day with what the results mean for the presidential election in November. On the one hand, Scott Walker has become a hero of conservatives. On the other hand, there are many ticket-splitters in the state. President Obama also didn’t campaign for the Democratic challenger and there are questions about whether spending contributed to Walker’s success. A Republican candidate hasn’t won the state since Ronald Reagan.

In other news, Mitt Romney swept the primaries in five states – California, Montana, New Jersey, New Mexico and South Dakota – increasing his delegate count to 1,398. The big news was the ballot shake-up in California. In 2010, voters approved a “top two primary” system in a ballot initiative, which was intended to stem partisan political gridlock and elect moderate candidates. Under the system, the top two finishers in the primary move on to the general election, regardless of party. The new system may provide stimulus for reform in other state and national elections.
