My co-worker can't keep political views to himself

[Xavier Breath]

5. The first sample you cited seemed pretty innocuous, save the last line.

But the examples you cite here are over the line of acceptable workplace chatter. At the next occurrence I'd remind him that you're both there to work and that, while a quick convo about the weather, the local sports team or what somebody's kid said last night is okay, you do not wish to engage in a political discussion. If he can't respect that then you've officially fulfilled your neighborly obligation.
