My hypothesis is that by raising an impotent fuss the Democratic leadership and friends feel themselves ‘strong’, and that this is ‘strength’ to them. They do not look at themselves through imaginary eyes of others, and they listen only to campaign advisors who have the mentalities of potatoes and yams.
Funny thing is that these pseudo-Democrats probably will win big in November despite themselves, because the ‘Republicans’ also are divorced from ‘reality’ in their own way and are harming themselves in their own way—but the Democratic leaders will convince themselves they won big because of their cleverness.
