It depends on how they gain people from the other party. The Democrats could gain them by giving them better health-care, or fewer wars, or by making the rich pay taxes, or by providing affordable housing, or by improving their jobs.

But the Democrat strategy is to gain them by supporting genocide, and attacking marginalized groups.
