The author seems to want to endorse Lakoff on some points but criticize him on others. This paragraph for me kind of sums it up:
I agree with this last insight wholeheartedly: Democrats lose when they think that they can win elections on data points without offering an inspiring vision of the future. Indeed, Lakoff has stumbled upon the central problem facing Democrats since Bill Clinton left office, but his explanation of how he got there is unconvincing, and his advice on how to go forward is misguided. By reducing American politics to language, Lakoff ignores the context that gives meaning to those words. Language only motivates people if the ideas and policies it's connected to resonate with a majority of Americans. It has to be consistent with the realities of American history and the American national character. Throughout his book, Lakoff ignores this context, using his theories to push for an agenda that resonates with him (and possibly his friends at the fringes of left-wing politics), but reflects neither what most Democrats—nor most Americans—believe.
The author agrees with Lakoff's emphasis on values and vision, but seems to be arguing that Lakoff's position on the issues is too far left for the majority of mainstream Americans.
Yet, the author doesn't really make a coherent case for it. He ties this to two specific cases -- tax relief and foreign policy. With the "tax relief" example he points out America's historic anti-tax bias as a way to say that Lakoff is too far left. The author misses Lakoff's whole point of the "tax-relief" example, which is to show that it is a FRAME. What does the historical basis of the anti-tax bias, although interesting, have to do with anything?
Lakoff here is primarily concerned with talking about this issue in a current context, not in an historic context.
Anyway. It's an interesting article, but I think Mr. Baer has missed Lakoff's point. His beef seems to be that Lakoff's position on the issues and/or his vision is too far left, but Lakoff is pretty much just offering us TOOLS to articulate our vision effectively. Lakoff's framing is mental jiu-jitsu, it's not a vision or a set of issues in and of itself.
