WordPress exclude posts from one query in another query

I have a page where I need to display posts with a custom meta key value of "original-document" in the left column and the rest of the posts from the category in the right column. You can see the page here http://www.constitutingamerica.org/blog/classification/the-federalist-papers/federalist-no-23/

The problem is that the posts tagged as original documents are showing up in the right column as well as the left column.

global $query_string;
$keys = array(
        'orderby' => 'ID',
        'order' => 'asc',
        'numberposts' => -1,
        'meta_query' => array(
            array  (
                'key' => 'document_details',
                'value'=>'original-document'
                )
            )
        );

$args = array_merge( $wp_query->query_vars, $keys );

$keys2 = array(
        'orderby' => 'ID',
        'numberposts' => -1,
        'post__not_in' => array($args),
        'order' => 'asc',
        'meta_query' => array(
            array  (
                'meta_key' =>    'document_details',
                'meta_value' =>    'original-document',
            'meta_compare' => '!='
                )
            )
        );

$args2 = array_merge( $wp_query->query_vars, $keys2    ); ?>

PHP:

I have also tried excludes and operators in my $args2 query and the original documents still show. I also though this would work in my second query but it does not work

$keys2 = array(
        'orderby' => 'ID',
        'numberposts' => -1,
                'exclude' => array($args),
        'post__not_in' => array($args),
        'order' => 'asc',
        );

$args2 = array_merge( $wp_query->query_vars, $keys2    ); ?>

PHP:

How can I exclude any posts from my first query from appearing in my second query?

 

This is entirely untested, but maybe you could try to actually pull out the value from the first $args-array, something like this:

$keys2 = array(
  'orderby' => 'ID',
  'numberposts' => -1,
  'post_not_in' => array($args['meta_query'][0]['value']),
  'order' => 'asc',
  )
