“Eighty-twenty!” said an upbeat Sen. Lindsey Graham, R-S.C., one of the key players in the talks, giving strong odds of a deal he said could be announced as early as Wednesday.

In a hopeful sign for a potential deal, Senate Majority Leader Harry Reid, D-Nev., postponed until Monday a vote that had been scheduled for Wednesday on bringing up an immigration measure that passed the Senate last year.
