What, Me Vote?
OK, it doesn't amaze me, but it still doesn't seem logical. Of course, once you are elected you really can't operate under any other assumption, but that doesn't mean you're not wrong.
In this country, about a third of those eligible to vote are actually politically active enough to vote regularly. There's your base: half of these regular voters. You can count on them as long as you don't do something stupid.
It's the fifth of all adults who vote once in a while that you really need. Convincing them of your position won't convince them to vote for you, nor will that strategy work for your opponent. They don't know much about the issues, nor do they care much about politics. What gets them to the polls is anger.
