I agree turn out sucks, that's not the campaign's fault. Dem voters just don't show up, they haven't and won't in midterms.
I just find it funny that we whipsaw back and forth between dems are amazing campaigners to dems are lousy campaigners.
the voters aren't there for dems to win and if you think that 'owning accomplishments' (2010 says hey!) or running farther to the left I don't know what to tell you. Your pushing what you want onto what happened. Like I said, its a mirror of the 'we need a more conservative candidate" on the right Its the go to reason because its solution is what you already want and have wanted and you fit the data to that (our base didn't turn out so we need to double down on them!)
Republicans in the south and much of the midwest have become the democratic party of the 20th century. The only choice, with the debates happening inside the party, not between dems and republicans (rubio vs. cruz on immigration, cotton vs paul on fp). Its become cultural and its solidifying and dems are letting it by retreating to their costal enclaves when they lose. GOTV isn't working by any large stretch (though I think there have flaws in my interaction with dem campaigns on how they're running this)
I think the best thing is outreach to middle america and a shift by the party away from focusing on cultural issues, there's no need for the candidate to make such a big issue out of them like udall did. We won the gay marriage debate, we're going to win the pot debate, people understand the war on women and by and large we have their vote. We're alienating white suburban voters who don't really care much on these issues and feel that we have no plan, because we don't. We don't need them in presidential years but we sure as hell do in midterms and much of the liberal blogosphere is really ignorant of why they vote they way they do and why they're voting republican.
