Gallup says that even includes Democrats:

Americans' concerns about the threat of big government continue to dwarf those about big business and big labor, and by an even larger margin now than in March 2009. The 64% of Americans who say big government will be the biggest threat to the country is just one percentage point shy of the record high, while the 26% who say big business is down from the 32% recorded during the recession.Relatively few name big labor as the greatest threat.

Historically, Americans have always been more concerned about big government than big business or big labor in response to this trend question dating back to 1965. Concerns about big business surged to a high of 38% in 2002, after the large-scale accounting scandals at Enron and WorldCom. An all-time-high 65% of Americans named big government as the greatest threat in 1999 and 2000. Worries about big labor have declined significantly over the years, from a high of 29% in 1965 to the 8% to 11% range over the past decade and a half.

Democrats Lead Increase in Concern About Big Government

Almost half of Democrats now say big government is the biggest threat to the nation, more than say so about big business, and far more than were concerned about big government in March 2009. The 32% of Democrats concerned about big government at that time -- shortly after President Obama took office -- was down significantly from a reading in 2006, when George W. Bush was president.

By contrast, 82% of Republicans and 64% of independents today view big government as the biggest threat, slightly higher percentages than Gallup found in 2009.

I think we have the Tea Party to thank for raising the alarm about how big government was truly becoming. But those numbers on Democrats thinking the same is also significant. The majority of Democrats are not Nancy Pelosi-Barack Obama type Democrats. Most are working people who are loyal to the party but are "persuadable" if a Republican speaks their language and wants to address some of their issues.

If the GOP nominee can capture a significant portion of these Democrats, Obama will lose in a historic landslide.
