Keep dreaming. There is zero chance the democrats will flip the House in 2014.
Obama has done some good things for the economy but dems are horrible at selling them because they are not pro-poor/littleguy fiscal policies. You seem to think that Obamacare and guns will not be the issues for 2014. I disagree.
You are very observant, I can't really disagree with any of that.
By the time that the 2014 election rolls around, most likely Obamacare will have been proven to be not much of anything. Obamacare will effect less than 2% of our employers, and only something like 15% of our workers. The good and bad will more or less set each other off, but most of the bad has already been factored into the market (lower job growth, higher insurance rates, etc). Basically, Jan 1st 2014 will come and go, and very few people will see any difference. For republicans, part of the problem is that they have so hyped up that "the economy is going to be wrecked" by Obamacare, and when it doesn't get wrecked, they are going to be made out to be fools. Thats not going to make any difference to tea partiers and hard core republicans, but it will shift many of the 30% of our voters who are moderates or swing voters to the left. Now don't get me wrong, I think that Obamacare is largely a step in the wrong direction, I prefer a true free market based solution to our healthcare "crises". I actually met with my congressman, who is a republican, and made a pitch for a totally different solution to healthcare, that didn't involve any additional taxes, and was very much based upon letting free market competition keep health care prices in check.
As far as that "pro-poor" stuff, democrats have never been "pro-poor", yet the poor have been voting for democrats for 70+ years (and of course they are still poor, a lot of good that did them). The fact that our current generation of democrat politicians are just as anti-poor as their parents were will not make a difference to the poor, because the poor also happen to be pretty much stupid (which is of course a big part of the reason that they are poor to begin with).
Where Obama CAN pick up a lot of votes is with the middle class. If he is able to get tax cuts for the middle class, he will come off as a hero to the middle class, regardless of their party affiliation. It should be fairly easy to accomplish because republicans can't vote against it, or else republicans will appear to be the villans. Now naturally republicans will try to steal his thunder, by claiming that they had to fight those "tax and spend" democrats to get the tax cuts passed, but the public is likely to see through this, just like they are apparently seeing through this smokescreen of "scandals" that republicans are trying to bring Obama down with.
So going forward two more years, due to the energy boom, and lower taxes on the consumer class, our economy should be fully recovered from the Great Bush Recession, and Hillary, or some other democrat candidate for POTUS will be virtually unbeatable.
