Argument #2: You probably need something like ten kilobytes of information to make a reasonable decision about which presidential candidate to vote for. This is way less than the amount of information that news-oriented people spend their time and attention to absorb on a single day.
(If you want to overkill, on November 1st you could read the election issue of The Economist cover to cover, whatever political posts are on the front page of HN, and the Wikipedia pages for the major issues. Then sit and think carefully for an hour. This would take about five hours, and I’ll bet $1 you’d vote for the same candidate you would have if you’d read five hours of political news per day for the last year.)
