I would not go so far as to say Reagan was overall left-wing, but he did some things are are very left-wing and also had a huge impact and weren't minor at all. California has been a blue state since his immigration amnesty, this was not the case before - it was usually solid red.
Was Bill Clinton "right wing" because of his free trade politics (eg NAFTA)?
Contemporary left-wing politics do not look like communist Russia when it comes to the economy. The American use of the term "liberal" (or "liberalism") is more useful in that regard, and that includes free trade, and also immigration of foreign labor, something that naive observers might categorise as "neoliberal" or "turbo-capitalist", except that many left-wing governments engaged it in (US, Canada, UK and many more).
