This retooling sounds suspiciously like the advice the conservative pundisphere was ramming down his throat last week. Some top conservative writers called out by name Romney adviser Stuart Stevens, blaming him for the cautious nature of the Romney campaign.
Hopefully the part about getting more specific on policy is true. The Romney campaign seems to believe that November 6 being a referendum on President Obama is enough. Democrats thought the very same thing in Wisconsin about Scott Walker. It didn't matter who was running against him, he just had to go and a majority of Wisconsinites think so. Except that they didn't. Tom Barrett still didn't make his case for why he should be governor. Absent that, voters stayed with Walker.
The reality is voters in nationwide will likely do the same. The difference is Romney has a case to make where Barrett didn't. It's time to make that case.
