Would the Dems have won if they followed this ancient advice? 
A Chicago Tribune Columnist wrote an article why the Dems lost this election. In my opinion, his explanation is an affirmation of this 3000 year old proverbial advice.
King Solomon
He who stops his ear to the cry of a poor man will himself cry out and not be answered. (Proverb, 21:13)
You Decide
If interested, read the Chicago Tribune Article and a previous post below. The proverb states ‘poor,’ however, this election was more about the government elites not listening to the ‘middle class.’
Regards and goodwill blogging.
