I disagree that this will not be helpful. The old-guard of Democratic Party hails from these hyper liberal areas (Fienstein, Schumer, Pelosi), and based on what we have seen so far, they aren't even showing a slightest hint of resistance to Trump. See the senate democrat's response to Trump nominees for example. Put enough pressure on them, they will at least form a semblance of resistance which can inspire and have real effects.
For a practical example, if people of San Francisco jointly decide that they want Nancy Pelosi to do X, Y and Z (otherwise she will get primaried in 2018), she will have no option but to do that. This is exactly what the Tea Party did (with tremendous help from Koch brothers) in last eight years. They unseated the old leaders and took over the party.
