No sure who, but it is the point of the thing.

It may not be Kasich, who has been neutral so far, but a switcher instead, according to BuzzFeed:

A top Ohio supporter of Governor Mitt Romney will switch sides and endorse Rick Santorum in Columbus this afternoon, a campaign source said. …

While Ohio Gov. John Kasich remains neutral, Romney has the support of a handful of top current and former Ohio officials, including Attorney General Mike DeWine, Rep. Jim Renacci, and former Senator George Voinovich.

Voinovich is more center-right than conservative, which would actually play in Santorum’s favor. A switcher always has some impact, but we’ll see soon enough how significant the endorser is. Also, I wrote “Pat Toomey” when I meant Rob Portman, and I’ve corrected it above.

The house of moderate is falling. Milquetoast for everyone!
