Can Democrats overcome Electoral College outcomes by a policy of relocating liberals to non-liberal states?
I think Sarah Silverman tried to do this with a tongue-in-cheek invitation to Jewish grandparents to head to Florida. Could it work on as broader level? Unlikely. The amount of organization needed would be daunting and Republicans could counter with a population transfer move of their own. However what concerns me is that you appear to be looking at human beings as cattle - various dictators have tried such approaches - but would you really want to live in a country governed by a Party who sees such a hideous approach as a way of maintaining and winning power?
