In 2008, Obama was elected and both houses were Democratic. When he leaves office the presidency and both houses will be Republican. May I suggest a great deal of the blame is due to – wait for it – a comatose and complacent Democratic Party that continually moves to the right to attract Republican moderates rather than strongly support its traditional working class base. This strategy has been a disaster.
Trump at least pretended to care about the struggling lower 50% and yelled loudly he will help them. And they listened and responded.
