Fact checkers get FACT CHECKED!

I found this interesting article that related to something I had discussed before. Fact Checkers. What or who is it? 

A fact checker is the person who checks factual assertions in non-fictional text.

(Thanks Wiki)
Anyways, I had a discussion about Paul Ryan's speech a couple days ago with Niorgie and Ms. Blatteau and we found an article where Paul Ryan's speech was fact checked. Here's an example. Quoting Ryan's speech.

"A lot of guys I went to high school with worked at that GM plant. Right there at that plant, candidate Obama said: "I believe that if our government is there to support you ... this plant will be here for another hundred years." That's what he said in 2008."Well, as it turned out, that plant didn't last another year. It is locked up and empty to this day. And that's how it is in so many towns today, where the recovery that was promised is nowhere in sight."

Pretty much saying that it's Obama fault and that he lied about the plant staying in production. The plant closed December of 2008, a month before Obama took office. Which means that it's not Obama's fault.

After we reviewed the article, it got us thinking and it definitely raised a few questions. How many Americans, as Niorgie would say, would stand on the sidelines and actual do some research? How would this effect the polls? Anyways, I did some browsing of the web, Google-ing fact checker, I came across this interesting article, Fact-Checking the Fact checkers on Ryan's speech.

In that article I found out that the GM plant was actual being notified of pending closure in December of 2008 and was finally shut down in 2009, meaning that at the time, Obama was president and it was indeed his fault. So it was a game of back and forth on that claim but who knows how many other facts need to be checked.

Any thoughts?
