The GOP Pundits and Romney campaign only have two general excuses

[cleduc]

1. We lied.
2. We're incompetent in reading polls.

Dick is has to go with #1 while avoiding #2 because reading polls has been his only gig to get money. In his case, admitting he lied is the lesser of two evils for future income.

Rove can't admit #1 because admitting he effectively defrauded the billionaires would affect his ability to raise money (his power) in the future so he's got to blame the polling experts.

But Rove is in real trouble because Nate Silver, Dr Sam Wang, Drew Linzer and now Dick Morris prove that the polls could be read accurately.
