Is Mark Warner seeing dangerous numbers?

I couldn’t help noting that Mark Warner, the Democratic senior senator from Virginia, was one of the six Democratic senators calling for “hardship exemptions” for people finding Obamacare insurance policies too expensive, and also one of the 13 Democratic senators who co-sponsored the bill imposing tougher sanctions on Iran if, after the six months of negotiations under the not-yet-final interim agreement, it doesn’t agree to certain conditions.

Barack Obama has bowed to the six senators on Obamacare, further unraveling his premier legislative knitwork, but has suggested that the sanctions bill sponsors are only interested in electoral politics.
