The editorial board of the Indianapolis Star endorsed U.S. Sen. Richard Lugar, R-In., Sunday over state Treasurer Richard Mourdock in the hotly contested May 8 Republican primary.

In giving the six-term incumbent the nod, the newspaper responded to four chief objections to Lugar’s nomination raised by his Tea Party challenger and his supporters. Among the chief complaints from conservative activists is that Lugar is a disloyal Republican who party leaders can’t rely on.

From the Indianapolis Star:

Our response: Lugar has voted with the Republican majority in the Senate 88 percent of the time for more than 20 years.

Is a 12 percent deviance from the crowd really a sign of disloyalty? To us, it’s more of a testament to careful consideration of complex issues. No political party — Democrat or Republican — gets it right every time

The op-ed writers argue that few lawmakers have tackled “complex matters” with as much “thoughtfulness and vision” Lugar and he deserves another term in office.

UPDATE: Not to be outdone, the Mourdock campaign has an endorsement from the Evansville Courier & Press.
