I know I'm just a blogger at this rather non-descript little blog, but what Res says.
Again, the problem with losing in Massachusetts -- a very blue state -- is that enough blue voters look at the Democrats, Congress, and yes, the Obama Administration and wonder, "why bother?". From their perspective, why get out and vote for a bunch of guys who seemed trapped in the box of "we can't get those votes, so why even try for what we believe?" (warning, naively assumes beliefs).
Not a great way to motivate the ol' base.
So Democrats, you've got ten months -- I suggest you at least start dispensing the shinola.
