Conservatives don’t answer telephone polls.

Conservatives don’t answer telephone polls.

Gallup, once America's most trusted polling service, removed themselves from all political polling following the 2012 elections. They said that due to changes in technology and habits, it was not possible to get accurate polls. People don't answer their phones anymore. Gallup also said pollsters may need to return to 1920s and 1930s polling methods like walking door-to-door, but this is more labor intensive and expensive.
