The Pope is too liberal for regressives

See this article. A recent bill introduced in the house honoring the Pope for his stance on redressing inequality and promoting solidarity, most famously in his diatribe against trickle-down economics. Only 19 of the 221 backers are Republicans. One of those Republican backers speculates that there aren't more from his Party because those remarks a economics seem too liberal to most of the regressives. Recall that the regressive frontman for their Party, Rush Limbaugh, called the Pope a socialist and there you have their recalcitrance.
