Why Puerto Rico(PR) Has Been A Colony(None Incorporated Territory Of USA) For Most Than 123 Years Ago Since 1898??

thats what they say but on this planet puerto rico never had anything to do with the united states.

Because they have voted several times not to become a state.  At some point it may be, the citizens last few votes were close to passing but it's nearly a 50/50 split at this point.

Puerto Rico voted on whether to become a state or not and chose to remain a territory.

Irrelevant.

There are frequent elections which ask the people of PR if they want to be a state, stay a US territory, or become independent. In all of the elections so far, about 47% want statehood, 47% want to stay a Territory, and 5% or less want independence. 

Realize Puerto Ricans are full US citizens but they do not have to pay federal income taxes. 

A U.S. territory can become a state

A - if it meets the qualifications set by Federallaw (which P.R. does)

B - AND if it votes to become a state (which P.R. has never succeeded in doing, though votes have been held in the past)
