According to one Wikipedia "editor" (otherwise known as anybody with an Internet connection), John McCain — the senior United States Senator from Arizona and presumptive Republican Party nominee for President of the United States in the 2008 election — may have stolen large chunks of his speech on the current conflict between Russia and Georgia directly from an article Georgia on Wikipedia, a free,[5] multilingual, open content encyclopedia project operated by the United States-based non-profit Wikimedia Foundation.

Political Insider gives examples…

First instance:

one of the first countries in the world to adopt Christianity as an official religion (Wikipedia)

vs.

one of the world's first nations to adopt Christianity as an official religion (McCain)

Second instance:

After the Russian Revolution of 1917, Georgia had a brief period of independence as a Democratic Republic (1918-1921), which was terminated by the Red Army invasion of Georgia. Georgia became part of the Soviet Union in 1922 and regained its independence in 1991. Early post-Soviet years was marked by a civil unrest and economic crisis. (Wikipedia)

vs.

After a brief period of independence following the Russian revolution, the Red Army forced Georgia to join the Soviet Union in 1922. As the Soviet Union crumbled at the end of the Cold War, Georgia regained its independence in 1991, but its early years were marked by instability, corruption, and economic crises. (McCain)

That's kind of damning. But I think what really tips it off as being stolen from Wikipedia is that it's totally wrong.

Everybody knows that Georgia is a state in the Southeastern United States and was one of the original Thirteen Colonies that revolted against British rule in the American Revolution. It was the last of the Thirteen Colonies to be established as a colony, in 1733. It was the fourth state to ratify the United States Constitution, on January 2, 1788. It seceded from the Union on January 21, 1861 and was one of the original seven Confederate states. It was the last state to be readmitted to the Union, on July 15, 1870. Georgia is the ninth-largest state in the nation by population, with an estimated 9,544,750 residents as of July 1, 2007. It is also the third fastest-growing state in terms of numeric gain and fifth in terms of percent gain, adding 202,670 residents at a rate of 2.2%. From 2006 to 2007, Georgia had 18 counties among the nation's 100 fastest-growing counties, the most of any state. Georgia is also known as the Peach State and the Empire State of the South. Atlanta is the most populous city, and the capital.
