Because?

Because Obama can't improve his standing in that demographic between now and November?

Given his improvement in most demographics that have gone heavily for Clinton in the weeks between OH and PA, it sure seems like he might have a chance to improve his standing in the months befoe November:

                  OH   PA

60 and older      28   38
White             34   38
White men         39   44
White women       31   34
Less than $50K    42   46
No college        40   38
College           51   49
Catholic          36   31
Protestant        36   53
