Rights are distributive (with our Freedom of Association).
A x C + B x C = (A + B) x C
A = me
B = you
C = the right of Free Speech, in this example
Us speaking together is the same as you and I speaking separately, as far as the government should be concerned. To remove the C factor from the rhs, is to also remove it from the left.
An AC posted to my last JE, a kind of user I don't normally read posts from, but I was convinced he is someone who is on my Friends list. Because my response got long, and by posting AC he might not see it and notice the opportunity to say how I'm wrong about something, I've just made a new JE out of it.
If an entity doesn't get to vote in the ballot, that entity has no business influencing votes.
But the entities we're talking about here are not some kind of disembodied mysteries. They're us. It's a violation of my rights to have to shut up because I formed a business with someone or joined a union or a church or whatever. I as a legal citizen of the U.S. have the God-given right to free speech, of which political speech is especially "sacred" (in a democracy), no matter my associations.
Okay, that is, except in the capacity of an agent of the government. Our rights (are designed to) protect us from government, so if you take a job with the government, that's voluntary, and you don't have free speech on the job. So cops can't proselytize while they're writing you a ticket, and teachers, well, shouldn't be allowed to brainwash kids with their Leftist garbage. But if I want to run a grocery store where the check-out people try to convert you, or tell you who to vote for, that's my right. (And then you can decide whether to shop there or not.)
I'm okay with politicians being beholden to corporations. Or unions. Or environmental groups. Or the NRA. Or the Mormon Church (I'm not Mormon). As long as that makes them also aligned with their constituents. And if it's not, then bad on the voters. How can we expect accountability for politicians when we won't hold ourselves accountable?
A politician comes into office with (hopefully) some dead-set beliefs, and some that they haven't gotten all the information on yet and are potentially swayable (or are issues they just don't care about either way). The most concerned about an issue raise it with their representative, and attempt to persuade him/her. Those that aren't really concerned about an issue, don't. So the politician decides based on which side of the issue seems the most important to his/her constituents.
Lobbying is pure, wholesome Americana. You can pay someone to do it, or do it yourself(s). On an FNC special one weekend during one of the more recent times the EPA or whatever was trying to make life hard for a rancher, members of the family flew to D.C. to speak to someone to state their case. I personally think it's ridiculous that they couldn't get time while their rep was in town, and that legislators should be part-timers somehow, but I haven't thought that completely through and it's a separate issue.
But special interests, despite thinking certain ones are okay and others are not, is what we all are, and is not a reason to shut people up in violation of their rights. I for example am a walking set of special interests like, as a male I would like to see equality in reproductive rights among others, as a programmer I want the importation of competing slave labor stopped, etc. If I form a software business with some people, I would want those who would apply progressively more and more costly regulations on that venture with my life's savings at risk to not be elected. Denying me free speech, in whichever of my private capacities I'm engaging in, is immoral.
Without knowing the person, if someone says free speech is okay only except for corporations, to me that's not so much a position on speech as it is on corporations. If someone thinks corporations are evil and therefore should be excluded from x (among others), well, to me that's not a reason. I don't like the vast millions that the unions donate or that George Soros' various front groups donate, but I believe they have the right.
p.s. On a much less serious note, in case anyone reading this missed it, a couple of funnies (well of course I think the first one was funny): http://slashdot.org/comments.pl?sid=6180957&cid=48459463
