Not even Reagan shrunk the size of government. Is he a liberal too?
Trump wants to cut taxes. Enough said.
This shrinking the govt' meme has been mis-characterized for a long time. Reagan was not an anarchist (they are actually full on against any sort of govt).
Reagan was for a less intrusive govt in key areas of American society and was against the welfare state. Reagan was not against building roads, infrastructure or national defense spending and he was for some social welfare spending but against other kinds that enforced laziness and dissolution of families, etc.
