Footer widgets squished to left?

Is there some way to tell the footer widgets to display evenly/justified to the page width? No matter how many columns, widgets or different types of widgets I add, I can’t seem to find a combination that will show the footer widgets evenly – instead of 25%/25%/25%/25%, it does something like 15%/15%/15%/15%/40% ….which looks awful!
If I put in three or four blocks/widgets across, it still just squishes all of them to the left, adding an additional empty space on the right, and the page looks broken.

Am I missing something? Is there no way to fix this? It looks terrible ??
