Well, I thought it very intriguing in that the budget really lays out kind of a shocking attack on seniors, if you will. And we haven't seen all the detail yet, and we'll look at it, but I'll tell you, when you're going after seniors the way he's already done on Obamacare, taking $700 billion out of Medicare to put into Obamacare, and now coming back at seniors again, I think you're crossing that line very quickly here in terms of denying access to seniors for health care in districts like mine, certainly, and around the country. I think he's going to have a lot of pushback from some of the major senior organizations on this and Republicans, as well.
From the Repuclican House leadership

House Republican leaders did give Obama credit for including something known as chained CPI in the spending plan, which would slow the rate of growth for Social Security benefits. They were on message in calling for Obama to help them enact policies they agree on, without coming to terms on a large-scale deficit busting package.
The usual suspects have naturally been hollering about this for weeks.
