I just wanted to note work on framing from WSJ/NBC and Democracy Corps. These data that test attacks and counter-attacks suffer from the same basic problem of ice cubes and blizzards. However, since it is a Democratic group testing out language Democratic candidates are being advised to employ, I think it does deserve noting. Moreover, Democracy Corps found that the Obamacare attack didn’t seem to move voters *that* much.
It also deserves noting your key point about issues and trade-offs. Medicare was powerful, but other attacks like middle class taxes, Medicaid, and health care were as well.
Also, in this bipartisan poll for WSJ/NBC, the GOP argument lost by double digits in contrast to the rough parity in the Resurgent Republic poll.
