The Liberal Democrats' Demographic Smugness

Before the 2016 national elections, many liberal Democrats displayed a smugness that the demographics were on their side. What is truly amazing is that some liberal friends still have this demographic smugness about future elections.

Two points are worth considering:

1. Although the country is becoming less "white," it is not becoming less male. Even immigrants and non-whites are roughly half male. Unless the Democratic Party starts focusing on "men's issues" as well as "women's issues," some men of all ethnicities will drift away from the Democratic Party.
2. Liberal Democrats seem to assume that the Republican Party will not make adjustments because of the demographics. With Trump, Hispanic voters shifted Democratic. But, imagine if the Republicans stop trash talking immigrants and run Latino candidates? A lot of immigrants run small businesses and certain parts of the Republican platform might look appealing.
