sorry, wikipedia won't do it.....wikipedia is as likely to be false and misleading as it is to be right and forthright.
Wikipedia is little more than a free-for-all blog.....
Actually that is not true. It's a good idea to take whatever you read on Wikipedia with a grain of salt, but that is true of everything one reads. At least Wikipedia has procedures for ensuring that false statements can be corrected.
In the statement I quoted, they stated specifically where Robert W. Welch called Eisenhower a communist. You can consult this book yourself and find out whether this is true.
Furthermore the article mentions that William F, Buckley, Jr. criticized the accusations of Welch. Buckley is not an unknown person and it would be easy for you to determine whether he said these things. So you can see that Wikipedia has provided information that allows you to focus your research.
