There's an article out from the Cato Institute that says we could balance the budget in 10 years if we restrained spending increases to 2.5% annually. Show me the liberal who will say anything about restraining spending. It's not unrealistic, except to liberals whose answer to everything is higher taxes and more spending.
I'd like to see that article if you can find it. As for liberals talking about restraining spending, I guess you totally forgot Obama exists (or you don't consider him a liberal). What do you think the Simpson-Bowles catfood commission was about? And if you think massive cuts to Social Security and defense are politically possible, I don't know which country you're living in, because it definitely isn't this one.
Here's your link. I started a thread about it a few days back.

Seriously, you've giving me Obama? Sure, he talks the talk, but have you seen his budgets? No spending restraint there, and the man totally ignored and discredited Simpson-Bowles. You're a total joke, you really think Obama would cut spending or limiting it? Sure, when pigs fly.
Why would you think Obama wouldn't be willing to cut spending? He signed the preposterous Budget Control Act in to law. He was willing to accept deep spending cuts until Boehner left the table because he found a single penny of tax increases to be unacceptable. Obama didn't embrace Simpson-Bowles because Simpson-Bowles was intended as a compromise measure. It would have been foolish to make the compromise proposal the left flank.
