Trying to align list items in sidebar

I created a theme based on my companies corporate website. I have everything looking the way that I want it apart from one remaining thing, the sidebar list items:

I want to move the items over to the left so that they are only indented a couple of spaces. can anyone help? I have tried all of these items in my stylesheet:

div #sidebar li {list-style:none;
padding-bottom: 0.5em;
padding-right: 0em;
padding-left: -1em;
margin: 0;
list-style-type: none;
margin-right: -1em;
}

div #sidebar ul li {color: #FFFFFF;
font-weight: bolder; text-align: left;}
div #sidebar a { color: #FFFFFF; text-decoration: none; font-weight: normal;}
div #sidebar a:hover { color: #e17d2a; text-decoration: underline; font-weight: normal;}
div #sidebar ul ul li {color: #FFFFFF;
text-decoration: normal; text-align: left;}
div #sidebar ul {color: #FFFFFF;
text-decoration: normal; text-align: left;}

div #sidebar li {color: #FFFFFF;
text-decoration: normal; text-align: left;}

Any one have any suggestions?

Thanks so much!
