Italian-Americans tend to lean Republican nowadays. So do French-Americans, Greek Americans, and Irish-Americans for that matter. Polish-Americans are 50-50, but they went for Trump. Greeks, Italians, Poles and the Irish were Democrats for a very long time in this country. I don’t have figures on any other groups.
Frankly, most if not all White ethnicities have been voting Republican for some time now in the US. This has been happening ever since the Reagan Democrats.
