I don't remember libs complaining about this when the non voters handed the election to obama, twice.
Do you really believe conservatives sat it out in 2008 or 2012? They showed up. Its the young and poor who don't show up for midterms.
You lost those general elections because more people showed up. Republicans always lose when voter turn out is high. That is why they want to suppress and/or discourage voting. Like when they say it doesn't matter. They want you to believe that but they know it matters.
For example, the economy is doing great! How come that hasn't won over any conservatives? Because they don't care how good the economy does. In fact, for the economy to do better, we'd need to take some of the money the rich are sitting on and spread it out to the masses. In other words, tax the rich and corporations more.
Sounds to me like you're trying to pick apples in the cherry orchard.
You can't blame the 2014 loss on the failure of the young and poor to vote ... the numbers prove otherwise.
In 2008, Dems carried the young vote (18-29) by a 2-to-1 margin. In 2010, that margin decreased to 60%-38%, and held about the same in 2012.
In 2014, however, 21% of young voters actually cast their ballot (historically consistent for a midterm election). However, the Dems' advantage slipped to 53% - 38%.
In short, non-voters wasn't the problem ... the message was the problem. We even had some states where the overall youth vote went Republican. It's no accident that, in those states, Dems were tossed out summarily. (think states like Arkansas, Alaska, etc.).
There's no question that the voter base feels disaffected. They feel the government doesn't listen to them. The poor are upset that the current administration didn't give them more handouts. The young are upset that the current administration didn't give more handouts. When they didn't get what they want ... the bolted.
You can't buy loyalty ... you can only rent it for an election or two.
