How many Socialists Parties are there

There are a few, but none really popular (for now). We have socialistic ideologies growing, however, most overtly in the younger generation.

But we have them in major parties as well. Democrats are coming known for "democratic socialism" (which is really just socialism on their terms). And the GOP is known for economic subsidies which are socialistic in nature (farm subsidies, for example, would not exist in a purely capitalistic economy).
