Well, it would certainly increase representation for people who support policies that Republicans call "socialist", so the result will be more of those policies. I don't know what "full bore socialism" means to him, but socialism in general has a different definition for politicians than academics. For example, I'd consider the US to be more socialist (in the academic sense) than Scandinavian countries in many ways, yet people like Bernie Sanders use the term to describe policies they'd like to adopt from Scandinavia. Both sides get it wrong, with the right labeling everything they don't like with it, and the left trying to make the term more palatable, yet they both use it completely incorrectly. For some reason, when most people say "communism" they mean "socialism" and when they say "socialism" they mean "progressivism". Likewise for the opposite end of the current spectrum, where by saying "fascism" they mean "nationalism" and/or "protectionism", and by "nationalism" they mean "patriotism". Basically, they'll say whatever will get the biggest emotional impact, even if it's completely false (but has been used similarly in the past).
