This week, when McCain fired some lobbyists from his campaign, other lobbyists have been complaining how much this hurt them (italics mine):

More than a few Republican lobbyists in Washington are scratching their heads these days, asking: So this is the thanks we get?
It was a small band of loyal lobbyists who stood by presumptive Republican presidential nominee John McCain last August when his campaign went broke and his White House aspirations seemed doomed.
They raised money for him under impossible odds and kept him company in budget hotels during his darkest days.
Now they are under siege as McCain purges active lobbyists from his campaign team in a quest to wrest the reformist title from Democrat Barack Obama, his likely opponent in this fall’s general election…..
“If it was OK to have these people working for you in February, why is it not OK today?” asked one Republican lobbyist who counts a friend among the new McCain outcast class…
“McCain’s self-righteous [expletive] has caught up with him. Now he’s got himself in a jam,” said another Republican lobbyist who asked to remain anonymous because he is a campaign volunteer. “He’s got to change the subject back to economic growth and taxation and the war on terror.”
And there’s this thought from another McCain supporter: “I find it a little offensive. It was good enough to get my $2,300 donation. If we’re not good enough, then send my check back. It pisses me off.”

Oh Noes! Maverick McCain is not doing so well with his K street base. The lobbyist rats who want to jump Clinton’s ship are also having difficulties:

In his campaign for the Democratic presidential nomination, Obama is refusing donations from federally registered lobbyists and excluding them from his official campaign staff. (They can still be advisers and volunteers, and their spouses’ checks are certainly welcome.)
The Illinois senator’s lobbyist backers adapted to those rules months ago. But they’re creating some angst today for advocates who banked on Hillary Rodham Clinton’s campaign.
With it now sputtering, those lobbyists are scrambling to figure out how to ingratiate themselves with the Obama team other than with the classic political pivot: issuing a big donation check.
“The whole anti-lobbyist shtick is disingenuous and annoying on both sides,” said one lobbyist.

Actually, I think most Americans would find this refreshing, not disingenuous. You know, people who actually do something productive.
