You are correct, but with the rise of nationalism as an appealing ideology, there are fewer white working class liberals (AKA blue collar) than there were in the past. These people were decisive in the 2016 election, and were a big reason that swing states had close elections in 2020.
Many of them have abandoned universalist progressive economic ideas because of the loss of economic security they experienced with globalization.
Also, unlike the capitalist and professional classes, the nationalists are often OK with strong safety nets, as long as these benefits are limited to their tribe. They are really neither conservative or liberal. There are other political dimensions involved.
