It’s polls like this that make liberals nauseous.

PRINCETON, NJ — Seventy-two percent of Americans say big government is a greater threat to the U.S. in the future than is big business or big labor, a record high in the nearly 50-year history of this question. The prior high for big government was 65% in 1999 and 2000. Big government has always topped big business and big labor, including in the initial asking in 1965, but just 35% named it at that time.

The latest update comes from a Dec. 5-8 poll. Gallup has documented a steady increase in concern about big government since 2009, rising from 55% in March 2009 to 64% in November 2011 and 72% today. This suggests that government policies specific to the period, such as the Affordable Care Act — perhaps coupled with recent revelations of government spying tactics by former NSA contractor Edward Snowden — may be factors.

Currently, 21% name big business as the greatest threat, while 5%, a record low, say big labor. The high point for big labor was 29% in 1965. No more than 11% of Americans have chosen big labor since 1995, clearly reflecting the decline of the labor movement in the United States in recent decades.
