National Review has interest in the story I linked last week–that Manchin is under investigation. It could be something big, or a huge yawner. NRO’s Geraghty notes that Oliverio defeated the incumbent Mollohan on ethics issues. True enough. The suggestion is that if Manchin is also ethically challenged, the potential Republican opponent will have a great opportunity.
NRO says that Manchin is popular, and he is to an extent. I found it a bit surprising that, under a head-to-head with Capito, Manchin only received 53% of the vote.
Even without the ethics problem, Manchin is vulnerable.
