Multiple Selection Field: How can I expand the options when displaying 2 columns?

I have a checkbox field that I've set with 2 columns.

The problem is that the text for my choices doesn't stay on one line.

The entire field seems to have plenty of room to expand so there could be  2 wider columns  but it doesn't.

Shrink is turned off.

Attached is the screen shot. How do I get the longer text (indicated by red arrows) to stay on one line?

Please inject the following CSS code to achieve it: 

.form-multiple-column {

    width: 100%;

}

.form-multiple-column span.form-checkbox-item {

    width: 50% !important;

}

I hope this helps.
