iTheme2 Column Increases

Hi clever WordPress Peoples,

I’m wondering if there’s a way to increase my right column on iTheme2? I’m hosting a poll through Polldaddy and the narrow one is too narrow (for my taste) but the medium sized one goes out of the column width! Go to https://www.boringcapetownchick.com to see what I mean. If any clever css people have a code/idea for me, please let me know. Thank you ??
