Probably double down, because the alternative is accepting that what Trump was offering genuinely appealed to a large amount of people. That's what the Democrats don't get, that people weren't tricked into voting for Trump but thought/think he's more likely to improve the US and his policies could work. It's like the situation with the anti Brexit people in the UK. They physically can't picture a situation where people would want Brexit, so they desperately look for a scapegoat. Either way, there's no scapegoat or trick responsible here. The losing side wasn't offering what people wanted, and the winning side appealed to more people.
