The US political party system has no "right" and "left" -- it has "right" and "righter right."

At the grassroots level there is a bit of a "left" in the Democratic party, but it has no power anywhere.

EDIT: this is why it's twice as jarring to see Trump and the GOP ranting about the "radical left" in US politics. WTF? Where? Tepid neo-liberalism funded by Soros is... "left wing?" Wow.
