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.
