Do they need to get a room?

Tom and Mike are heading up an Electoral Commission campaign to get people to take an interest in politics and get out and vote. Apparently these two chums want to point out that when talking politics is off their social agenda their conversation quickly dries up. I can’t imagine a pair less typical of your average social group who seem to get by rather well without touching on politics at all.

This leads me to suspect that these two have little in common so one has to wonder why they continue to hang out together? What are they thinking during their extended pregnant pauses? What possible agenda draws the two down to their local haunt late at night?
