How to tell look-alike politicans apart.

There are various techniques reporters employ:

I used to make notes next to the names of members I was looking for — intentionally sloppy so they wouldn't be legible to the member as we huddled over my notebook off the floor of the House chamber — of their distinguishing characteristics. "Bald. Bald with glasses. Combover. Close-talker." And there is this classic method, offered by a former colleague on the beat: "My trick is, when you're talking to a member and you don't remember who they are, you ask at the end of the conversation — even if you couldn’t give a shit — 'And how will this affect your district?' So that way it narrows it down, and you can return to the picture book to look them up."
