Since I am old fashioned, I used the traditional American view about the right and left, and that guy is most definitely on the left.
In American politics, the right wing was really defined by three points
fiscal conservatives
religious conservatives
social conservative
On the first one, the Republicans still want lower budgets and tax cuts. Not all Republicans, but that is the party that still believes in smaller government and tax cuts. Imagine a Democrat campaigning on tax cuts.
On the second one, it is the Bible Belt, and they are red states right.
On the third one, everyone is gay!
Including Biden.
