Obama hasn't even nominated anybody yet, and all the Senate Republicans have done is make some vague recommendations. All this talk about the Senate not doing its job is a bit premature, innit? I think making statements and negotiating through the media is a quintessential part of a Senator's job actually.
If you want an example of the Senate not doing its job, I refer you to the last four years of Harry Reid's tenure as majority leader. The Senate didn't pass a budget resolution for fiscal years 2011, 2012, or 2013, even though a budget resolution is an important part of the budgeting process.
