Why is the ListBoxItem content indented to the left?

Question

I am sure this is something only my newb-ness can create, but, as seen in the screenshot, the border specified in the code snippet renders slightly indented from the left:

Here is the code for the data template:

    <DataTemplate x:Key="itemsTemplate">
        <Border BorderThickness="1,0,0,1" BorderBrush="Black" >
            <TextBlock Text="{Binding DisplayString}" TextWrapping="Wrap" Cursor="Hand" FontFamily="Tahoma" />
        </Border>
    </DataTemplate>

I added the border on the left to better illustrate the problem. What I really want is the bottom border to extend the full width of the ListboxItem. Why is it indented? How do I fix this?

Thanks!

In addition to DataTemplate you should declare this Style:

            <Style TargetType="ListBoxItem">
                <Setter Property="Padding"
                        Value="0"/>
            </Style>
