To add to my first posting--
the first website that i used: http://www.usconstitution.net/constamnotes.html#Am12 is still a very reliable source because after looking up the author, Steve Mount, i can see that he is very cabable of maintaining this website. He is the webmaster and researcher for the site and has credentials and experience in this area. Knowing his credentials and experience helps me to know that this site is okay to use for my own research because i can mostly trust that his information is correct. There are also a lot of other Constitution websites that link into this website so i know that it is helpful and correct because many other sites about the Constitution are using it too.

The 2nd website's information, http://en.wikipedia.org/wiki/Twelfth_Amend...States_Constitution, is provided by the Public Interest Registry, which sounds reliable however the PIR (Public Interest Registry) doesn't guarantee its accuracy, which is sort of sketchy. There is also only one website linking on to the wikipedia website however it is Wikipedia itself. This might be because it's an encyclopedia, but it's not to assuring knowing no one is linking into it. Because it is an encyclopedia, most of the information should be right, and the website does include a lot of information and i dont think it would be wrong. But just by evaluating the website it doesn't seem to be a very strong website to research the answer to my question.
