More Americans call themselves conservative than any other ideological label.

A new Gallup poll finds that 40 percent describe their views as conservative, 35 percent as moderate and 21 percent as liberal.

Gallup notes this is the third straight year conservatives have outnumbered moderates.

The 2011 results are based on 20 Gallup and USA Today/Gallup surveys conducted between January and December. They included interviews with 20,392 U.S. adults: 5,912 Republicans, 6,087 Democrats, and 8,064 independents.
