Oh please. The Democrats have lost the legislator handily both times since 2010. Meanwhile they have done nothing but blame everything on external factors. Voter apathy, gerrymandering, an off chance conservative revolution, etc. Sorry, but it gets a little old constantly playing the blame game.
"What can Democrats do?" There is no straight shoot victory for anything. However, a likely solution would be that they need to find ways to appeal to voters who lean Democrat but aren't gunho about them. The reality is that the majority of voters lean Democrat but a large portion of them don't vote due to being apathetic. This includes poor whites, immigrants, and Hispanics. Yet instead of targeting these groups they do stupid shit like trying to distance themselves from Obama and appealing to conservatives in the 2014 elections when they got slaughtered. Before that they underestimated the right wing after their victory in the 2008 election. It's things like this why people left the more moderate aisle of the Democrats in the first place.
So, you don't have shit either, gotcha.
You don't think it is their plan to appeal to more people like that? Just because they fucked up doesnt change the fact that that is their over-arching plan. And you act like if they didn't fuck up that it would have made a difference. Hate to say it but it probably wouldnt have because midterm elections always result in lower turnouts and usually result in lower democratic turnout and lower presidential party turnout/voters. There is only so much a major party can do to get people to vote.
