realclearpolitics.com is not a link to a poll, foxnews.com is not a link to a poll. Do you have a direct link to the polls? Are they online polls or actual polls?
Here is the Fox News poll. Real poll. It is a pdf file. You'll need Adobe Acrobat to read it. The results are nearly identical to Gallup yesterday.
