I don't think that's fair .. at least not in most cases. Politician is not just a job. It's a leadership role, moral leadership among other things. Being principled is a major component of the job they've undertaken. If a doctor found a discrepancy between his career and the welfare of his patients or a judge between his career and justice, I really do think they are morally obligated to choose selflessly.
Maybe it's naive, but I think it's possible to have a society where most judges are genuinely obsessed with being just.
The problem therein is that, at least in the vast majority of circumstances, everybody thinks that they are being "just", but their justice is always colored by their own personal morals, which may or may not conform to your morals or mine.
I'm sure that the judge who recently disallowed a mother from naming her child "Messiah" felt like he was being just, but that justice was undoubtedly colored by his religious faith.
The judges who uphold "traditional marriage" also probably felt like they were being just, as their justice is shaped by what they personally consider to be 'right' and 'wrong'. The law itself, in too many cases, offers too much ambiguity.
We want states to have the right to do things their own way on issues we want, but not on issues we don't. If we, as people, support the right of gay marriage, we think that states should be required to allow it. However, if we support marijuana is relatively harmless, we think that states should be allowed to legalize it.
These are just examples, but it's hard to come up with a 'pragmatic' solution for what is or isn't just. If justice is based on morality, then whose morality do we base it on? If it's based on whether or not it causes harm to others, then what level of harm do we allow? Freedom of speech is generally harmless, except when it isn't -- except when it's "fire" in a theater, or when it's your neighbors yelling at 3 am, or when it's someone preaching [religion/anti-religion] in contrast to what I want to hear.
In short, it's a very complicated thing, justice, with blurry edges, multiple middles, and an infinite list of value substitutions that muddy the issue. Even those doing the very best things for the most noble of purposes can be considered harmful by others who are also doing the very best things for the most noble of purposes.
I agree. It's hard. But think that's a different type of problem. This is not a case of disagreement about a moral question. This is a case of politicians choosing politically convenient over moral paths and effectively being dishonest about their judgment.
There are certain issues (drugs prohibition is a big example) where politicians often 'come out' about their true position after leaving office. They don't want to be the "weed guy," so they don't publicly support legalization while in office. This is different from genuinely disagreeing about the correct policy.
Even just honesty would be an improvement. "I think marijuana/gay marriage/whatever should be legal, but I don't think the majority want that/it's not worth pursuing right now/insert real reason they aren't pushing this." I don't think that's impossible. It requires a change from us. We need to be willing to let politicians openly hold a position while not pursuing it in legislation.
For example (I'm not American, so this is contrived), my view on the American gun issues is that widespread ownership of firearms for self defense is bad, but it's going to be very difficult to pursue disarmament effectively when so many people disagree so strongly.
I have, basically, the exact opposite view on firearms ownership, so take my reply with salt.
You're completely not wrong about political integrity being key to the process. At least speaking as an American, we don't seem to have any. I watched a neighboring state's election last night and the result was very close. Very close. Out of over 2 million votes, the opponents were separated by less than 60,000 votes in the outcome.
Of the two primary candidates, the winner was a notoriously corrupt politician who is well-known for being a political fund-raiser and (basically) morally bankrupt, while the other is more intellectually honest (at least, as comparing his statements to his voting record), but openly disapproves of things like gay marriage, and wanted to ban blowjobs. Even the libertarian candidate (and I'm a libertarian party member) was sleazy in too many ways.
Ultimately, the contest was won (predictably) by the one who spent the most money. Which means that fund-raising was critical, which means that getting in bed with money is necessary, which makes it nearly impossible to get intellectual honesty in elections. There are pretty noble efforts to eliminate, make transparent, or in some way normalize election contributions, but that just shrinks the list of viable candidates down to the rich, which isn't meant as an indictment of the rich, but isn't necessarily good for the interests of the hoi polloi either. Michael Bloomberg is rich, and he's been objectively horrible for New York City on a few landmark pieces of legislation (not meant as a comment on his entire term, but banning sodas? Really?).
As pertaining to firearms, that issue is, I think, more cut and dry. Our Constitution says we have the right to bear arms, and the job of our federal government, and its employees, is to uphold the Constitution, or to ratify it where it is wrong. The latter point is important, I think, because while I disagree with the notion that "guns are bad" (which is an argument for a different day, perhaps), I would abide the law if the Constitution were amended in the Constitutionally prescribed process. I wouldn't love it, but I am far more offended by those who would sidestep the Constitution to ignore its tenets.
Either there's support to ratify it, or there isn't. There currently isn't, but even if there were, none of the legislation proposed makes any attempt to uphold the Constitution, and all of the legislation, even that which I support, runs afoul of our governing tenets, and such be dismissed out of hand as such.
Maybe it's naive, but I think it's possible to have a society where most judges are genuinely obsessed with being just.
