A left-wing liberal wouldn't describe themselves as a 'conservative'. What are his positions on the State, extraction of surplus value, capital accumulation and democratic management of organisations that makes you so sure he or his manifesto is left wing?
Research papers cite scientific sources, sorry. Out of curiosity I've read the document being discussed here and clicked a random sample of the links and none of them I clicked led to peer-reviewed science (though a couple are Go links and a lot are Wikipedia).
The tone of the language is nice, but the Wikipedia citations remind me of my time teaching high school five years ago. Anyone who wrote a paper without citing in a significant way five scientific sources (google scholar provides free pdfs, how awesome is that?) got an automatic zero.
Wikipedia has good information but it's hardly what one would want backing themselves up for something like this.
