Here's Ezra Klein's reaction:
...if the transcript of the conversation is unexceptional, the fact of it is lethal. The state’s Democratic senators can’t get Walker on the phone, but someone can call the governor’s front desk, identify themselves as David Koch, and then speak with both the governor and his chief of staff? That’s where you see the access and power that major corporations and wealthy contributors will have in a Walker administration, and why so many in Wisconsin are reluctant to see the only major interest group representing workers taken out of the game.
Yglesias adds his two cents:
Imagine a world in which every single one of Scott Walker’s constituents had more access to Scott Walker than does a rich out of state donor. And imagine the richest man in Wisconsin had equal access to Walker as the poorest. Try to imagine it. I think that if we lived in that world, people would have a very different reaction to complaints about the disproportionate political influence of labor unions.
And Reihan chimes in with a somewhat different perspective:
I hate to tell you this, but I’m pretty sure that virtually all elected officials are willing to talk to campaign donors, rich people, and celebrities. Think about it. You’re basically the kind of person who ran for student body president, and suddenly really, really important people want to talk to you. Imagine how thrilling that must be! It should go without saying that this is completely pathetic. This is a big part of why we right-wingers think that politicians should have very narrow, circumscribed powers. They’re not an attractive bunch. Speaking only for myself, the politicians I come closest to admiring are the bona fide nerds who’d rather hang out at a diner in rural Indiana than talk to billionaires or celebrities.
