Thumbnails off to the right

I’ve looked through all the topics on here but still haven’t been able to figure it out. My thumbnails are showing up too far to the right, I think it may be some padding on the left? But I can’t nail it down.

Here’s the page: http://attackgaming.tv/mmo-articles/this-is-a-news-post-test-post-please-disregard/

You can see the ‘Popular Posts’ are not how i’d like them to be. I want the thumbnails to fill the sidebar.

Thank you!
