Nope. Like in that other thread (I forget which one specifically, there are many that discussed third parties), I explained to MThanded how some issues are more important to some people than others; perhaps to the point of breaking a threshold of irredeemability, or a firing offense, if you will.
Of course there are differences, if your pet issues take precedence over those differences, then there you have it.
If one thinks that the military-industrial complex, the prison-industrial complex, and corporate financing are at the root of many of the worst problems in America, then there isn't that much to differentiate the parties since they both have done their best to benefit from them.
Of course they are not the same in every way, but if what you care about consists of mainly the issues that you care about, then they are.
I have three main objections:
It is hard to imagine a voter who is capable of critical thought and investigation but concludes that the only salient issues are the military-industrial complex, the prison-industrial complex, and corporate financing. It is hard to imagine what life experiences, what balance of self-interest and empathy, what professional background and class and race and gender and religion, what profile would lead to that to be the case. I do not pretend that I know better than a voter what issues are important to them, but I can point out that particular combinations of issues to the exclusion of others are basically absurd and not consistent with the way real world people form opinions. Yes, people contradict themselves. No, people aren't entirely consistent. Yes, people compartmentalize. But despite this, awareness and relevance of issues are connected. It strikes me that a voter for whom those are the only relevant issues is either willfully blind to other issues or is materially misrepresenting their awareness of those issues and ability to contextualize them.
Second, it is hard to believe that someone would be concerned by the prison-industrial complex as embodied by the drug war, understand that it leads to the unjust detention of the urban poor and not see a particular issue--say, you don't like three strikes laws, mandatory minimums, racial disparities in drug sentencing, the death penalty, unequal access to justice, corrupt state judges, prosecutorial malfeasance, etc--that manifests itself in such a way that the two major parties aren't thrown into sharp relief. Whether or not the American political canvas is more limited than other countries, it certainly isn't limited to a vanishing point.
Third, and finally, I don't accept that even given that you choose an issue that presidential candidates are nominally identical on, that the outcome will be the same. You have a sense of who the candidates will delegate to. You have a sense of what kind of people in the room. You can research to get a sense of whether or not they're likely to listen to dissenting views in the room. You know that on many issues congress is important--and so perhaps this issue is well served by having a president who is better at cooperating with congress, or perhaps this issue is well served by having congress being incentivized to powerfully check the president. Even if both Mitt Romney and Barack Obama like puppies, they don't like puppies in the same way.
It's just interesting to see the rationalizing done once "one of our own" is in power. Given that the anti-war movement is a shadow of what it used to be, it can be argued that the movement was more anti-Republican than it was anti-war, and that the answer to the great moral dilemma of our time as many might have put it during the Bush years, is merely a matter of who's in office at the time.
I can't respond to this because "one of my own" is not in power. I'm not an American. I don't vote in the US. The guy in charge of my country is absolutely not who I voted for. In the US I would be most intellectually close to the green party. I don't want to represent anyone else on GAF so if you get the impression there are partisan democrats here playing the party game while using a veneer of objectivity, call them out. As long as you're responding to me, though, use my post history as a barometer rather than any pre-conceived notions you have about people holding a similar stance to mine.
