It could be 100%, but it won’t make much difference if there’s a Dem controlled Senate, and a Boehner controlled House.
The majority will mean nothing, though, if Cochran holds that seat. Maybe the powerbroker 'pubs will smarten up and get that nomination to McDaniel, this week at the latest.
I seriously wonder if Pubbies had 98 seats in the Senate, what are the odds it would be veto proof?
