Few Americans think it would be good for the country if there were more states, and most still agree that Washington, D.C. shouldn't be one of them. Support for making Puerto Rico a state isn't much higher.

A new Rasmussen Reports national telephone survey finds that only 12% of American Adults think it would be good for the United States to add more states. A plurality (44%) believes it would be bad for the country, while 24% think it would have no impact. Twenty percent (20%) are undecided. (To see survey question wording, click here.)
