Text appearing below navigational column

Presently, the text below the navigational column to the left of http://www.strongfamilies.us/links.php and every page of my site appears too many lines below the column leaving a gap. I would like the text to appear one line below the column but I don’t know how to do this. How can I fix this problem? Thanks.

The paragraphs are just wrapping around the floated sidebar, as is their nature, and that gap is not really avoidable.

Personally, I would take the main_nav out of the content div and float it left and the content div right, giving it a width of something like 680px;

#content {
  float: right;
  padding: 10px;
  position: relative;
  top: 0;
  width: 680px;
}

Thank you so much for your responses. This issue is now resolved!
