“Ideologically extreme”? Government is spending a peacetime record of 24 percent of GDP (the average since 1947 is less than 20 percent) and Democrats insist on spending more.

“Scornful of compromise”? Again, consider Ryan-Wyden — a compromise from Ryan’s previous budget — and watch the Left’s unadulterated scorn this week.

“Unmoved by conventional understanding of fact, evidence and science”? Mention the Medicare trustees’ report to Democrats, and they start accusing you of pushing grannie off the cliff. Math is kryptonite to these people.

“Dismissive of the legitimacy of its political opposition”? Read anything written by the Keynesian economics guru Krugman and you’ve got the Left’s standard posture today.
