Spending Problems And Democrats?

In 2008, the GOP released their "Pledge To America", detailing the state of the nation from their point of view and their course of action to remedy it.

Within this pledge was an acknowledgement of their own culpability in the spending attitudes in Washington and their pledge to change how they consider the payment for legislation. I take this as an apology to America for the behavior.

With the advent of the TEA party movement, many on the right are learning just how angry many Americans are at the taxation and wasteful spending which has shown itself in the mentality of wanting to ensure legislation is paid for prior to passage. I am not saying they are doing the best job with it, but at least there is an attempt.

My question is: has there been a Democrat since 2008 that has taken this step? Has any Democrat acknowledged their culpability in the reckless spending attitude and made any strides to change their own mentality?

I already know some of the expected responses, but am curious if I'll see something solid.
