In reality I think there is a lot of daylight between the parties on social issues that do not affect current power structures.
Abortion, trans rights, women's rights, gay marriage, religion in public schools, etc: Tons of difference.
Funding genocide, subsidising the fossil fuel industry, maintaining a for-profit healthcare system, opposing ranked choice or instant run-off voting, keeping third parties out, refusing to enforce anti-trust law, refusing to raise the minimum wage, no accountability for police brutality, etc: Broad bipartisan support.
