Due to the recent election, I looked up some stuff on wikipedia. This is more proof that they are wrong and can't be trusted.
Look at the pages of Joe Kennedy III and Patrick Kennedy. They can't both be true since only 1 of them can be the last Kennedy in public office.
Joe III is still technically in Congress until the new Congress is sworn in Jan 2021. Patrick left Congress in 2011 due to being unable to cope with being bi-polar and being in Congress.
Joe's page is correct and Patrick's page is wrong.
There are many more examples of factual errors on Wikipedia, without even getting into political biases.
