Why would David talk about the "liberal left"? There are no liberals who are not left, although there are those further to the left than liberals. So why then the term, "liberal left". It's for the same reason David believes Obama is promoting socialism. David does not know what is liberal, what is left, and what is socialist. Yet, he professes opinions on all of these things. Socialism seeks is common control of the means of production. If you find someone who thinks that's a good idea, they are probably well over 90. Liberal is belief that government needs to stand up to powerful economic concentrations and regulate them because otherwise they will do bad things to common person. That's why Liberals are trying to regulate Wall Street and are opposed by conservatives . Whether Obama's foreign policy ideas work or not remains to be seen. Ignorant labels won't help the analysis.
