These polls are probably the last thing that could really influence our *overall* forecast, if there's evidence of a shift in the generic ballot. Recently, those polls have been clustering in the D+6 to D+10 range, and that's right where ABC has it (D+8) among likely voters.
These traditional polls are generally very high-quality data, although note that they're not able to detect truly last-minute movement—a poll released today will have been in the field late last week.
