What does the writer imply in this line from the excerpt?

the house, dooryard, barng woodshed was now all full, and when another crowd come i told 'em not to go away for want of room as the hog-pen was still empty.

politicians have no respect for others' privacy.
politicians have no sense of shame.
politicians are determined men.
politicians are foolish men.

The author states " the hog-pen was still empty". With this comment he implies that he considered politician to be at the same level as pigs.  They will wallow in fecal matter and crowd in to any space to get what they want.  He goes on to say that they are shameless and have no respect for privacy.  This also reinforces his portrayal of them as willing to cram themselves in anywhere regardless of the location or conditions to get information.  He considers them lowly, dirty and visualizes them covered in poop.
