The U.S. has now gone the longest period of time since the last state was admitted. To date it is just over 49 years. The previous longest period between admissions was just under 47 years - between the admission of Arizona and Alaska.
There are only 33 states admitted to the Union. It takes the President and two thirds of the Senate to concur to ratify a treaty necessary to admit a State to the Union. The best example of the fraud of there being 50 states is North Dakota, South Dakota, Montana, and Washington. The United State Senate was not even in session in November 1889. I live in Yakama. They call this Washington State. They claim their constitution was ratified in this state on November 7th and then was admitted to the Union on November 11th. This is a total fraud. I am going to throw the corporate washington state right off the damned continent.
Wow! Arizona was the last state in the contiguous US (lower 48 states) to be accepted to the US! Not exactly what you would have guessed!
