Is bipartisanship present in Washington?

>>> we'll hear more from our roundtable in just a bit. but first, i'm joined by two key voices calling for compromise. tennessee republican bob corker and missouri democrat claire mccaskill . welcome to both of you. senator, what's changed in washington? where is the room for real bipartisan to avert this fiscal cliff? does it exist?

>> i think it does. i think we understand that this is about our country first. and it really is a time we need to put politics aside, and it's going to be painful. none of us are going to get the deal that we exactly want. but we have to keep talking to one another. and bob and i have talked this week. i'm talking every day with my republican colleagues. what has to happen, though, there has to be a realization that if we do nothing, the republicans are going to have to live with the fact that they are willing to stop a deal all over a tax rate for the top 2% of this country. and, frankly, i'm really hopeful that doesn't happen. and i know bob feels the same way.

>> look, speak are boehner and leader mcconnell both have put revenues on the table.

>> let's just understand. everybody in washington says revenues. there's increasing your tax rates and there's finding other ways to raise tax revenue . and the distinction is important, because what republicans object to is raising your tax rates . your actual marginal tax rates . that's the distinction that you have to answer, right?

>> well, you can get there two ways. one of the ways is the way i proposed, which is closing loopholes. that's a pro growth way of getting more revenues from wealthy americans. and i think, david, before this is all over with, there's lots of mathinations. there's capital gains , dividends. and i think cooler heads will prevail. and i think we will resolve this. and that's the very best thing we can do to get
