What's wrong with being a center-center nation?

I like reading The Huffington Post from time to time to keep track of the far-left. As a proud-member of "just the left", we hate to see members lean too far (in fear that they might fall over). But THP also has some worthwhile reads. Robert Borosage's The Center-Left Nation might have been one of these--he makes valid points--but he makes a fatal flaw in his argument.
Borosage attempts to make the argument that the nation is leaning more towards the left than to the right. Reeling from the Bush Administration, I would be inclined to agree, but not because of Borosage's argument. He begins by recognizing that only 22% of the country recognize themselves as liberals; the rest are either conservative or moderates. He then relates the percentage of moderates who agree with liberals on key social issues and then states, "this is a center-right country, but only if you substitute addition for analysis. "
But what he doesn't recognize is that being moderate is the middle-class of the political world. Everyone wants to identify themself as one. It's an easy way to stay non-committed. Also, especially for a "Center-Left" Nation, we still dislike the word, "liberal". If you took into account the number of mis-identified moderates who are liberals-in-denial, then the number of conservatives and liberals would be much closer and affect the polling statistics that reflected moderates sharing liberal views. Without the 10-15% (just an educated-guess based on my own observations) of mis-identified moderates, then the polling data would be much closer to 50-50 (with a slight edge to center-left; so, it would be more accurately be identified as the center-center-left, or just rounded to the center).
I much prefer an argument for the center-left by using a box-and-whiskers plot in which neo-conservatives (the new face of the republican party) would fall on the far right and be considered outliers. That is an argument you can make.
