A reader in Massachusetts that I trust sends along word that each of the Boston papers will have a poll of the Senate race out this weekend. The Globe’s poll, he hears, will have Coakley up by 15 percentage points. The Herald poll, he hears, will have it much closer — Coakley ahead by 7 percentage points among all voters, Coakley ahead by only 1 percentage point among likely voters.

That’s a pretty dramatic spread. No word on whether the Globe poll was among all voters or likely voters.
