New York Times contributing op-ed writer Thomas B. Edsall this week calls on liberals to analyze their weaknesses through a review of the Republicans strengths.

He starts by listing a large number of Republicans successes, from elections to the House of Representatives to President Trump’s current domestic approval rating among his voters, to the recent Tea Party proposal and success with the tax bill.

With a clear warning to Democrats, Edsall presents conscientious research and analysis. He bases his opinion piece upon clear and precise language and abundant well-documented data. He tells Democrats to get rid of sentimental party identification and recognize gaps and mistakes. It is a convincing research piece.

The analysis is lucid, aided with concrete facts and accurate data and figures, it shows seriousness. Edsall is impartial; he does not take sides and does not identify with either one of the two major political parties.
