Polling system plugin not displaying properly on wide pages. Any ideas?

I just made this theme live on my site last night and found a pretty big incompatibility with another plugin. I use a voting plugin called WPolling System and it’s not displaying correctly on wide screens. Mobile views or smaller screens show it correctly however. I thought it was an issue between the related articles and this plugin, but disabling didn’t fix it. I then thought it was the sidebar, but I disabled that and it still doesn’t work right. I’m out of ideas.

Any help out there?

Here’s a page with an example: http://aftercredits.com/2014/11/big-hero-6-2014/

FYI, I was able to work with the plugin developer and resolve this issue.
