Another wild and wacky buzz word, thanks democrats!

Journalist John L. O'Sullivan, an influential advocate for the Democratic Party, wrote an article in 1839 which, while not using the term "Manifest Destiny", did predict a "divine destiny" for the United States based upon values such as equality, rights of conscience, and personal enfranchisement-- "to establish on earth the moral dignity and salvation of man". This destiny was not explicitly territorial, but O'Sullivan predicted that the United States would be one of a "Union of many Republics" sharing those values.[5]
Six years later O'Sullivan wrote another essay which first used the phrase Manifest Destiny. In 1845, he published a piece entitled Annexation in the Democratic Review,[6] in which he urged the United States to annex the Republic of Texas, not only because Texas desired this, but because it was "our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions".[7] Amid much controversy, Texas was annexed shortly thereafter, but O'Sullivan's first usage of the phrase "Manifest Destiny" attracted little attention.[8]
O'Sullivan's second use of the phrase became extremely influential. On December 27, 1845 in his newspaper the New York Morning News, O'Sullivan addressed the ongoing boundary dispute with Great Britain in the Oregon Country. O'Sullivan argued that the United States had the right to claim "the whole of Oregon":
And that claim is by the right of our manifest destiny to overspread and to possess the whole of the continent which Providence has given us for the development of the great experiment of liberty and federated self-government entrusted to us.[9]
