It's one thing for voters to make an informed decision to vote for repugnant Republican policies. It's quite another for them support Bush because they are mistaken about which policies he really supports, or because they are greviously misinformed about world events (e.g. believing Saddam to be linked to 9-11, or that WMD had been found in Iraq). We must simply give up on the first sort of person. But those in the latter group might switch sides if only they knew which party was promoting the policies they desired. These 100 facts would be a good place to start.
I've previously noted that democracy requires that voters be adequately informed. The current state of America shows just how badly things can go wrong when this minimal requirement is no longer met:
The primary function of democracy is not to elect good leaders, since nobody can predict in advance how a politician will perform. It is to eject leaders who have manifestly failed. The ability to remove leaders who turn out to be corrupt, dangerous, outrageously dishonest or manifestly incompetent is the primary privilege and duty of any democracy. And if any leader in our lifetime deserved to be ejected by voters, regardless of their ideology or political persuasion, it is surely President Bush.
Perhaps the facts wouldn't help. Perhaps most people would continue to support the Republicans even after forming a more accurate conception of them and their policies. But, from a partisan-left perspective, it's got to be worth a try -- it sure does look like the truth is on our side. And from a non-partisan perspective, the result doesn't matter: informed support is intrinsically preferable to the ignorant variety that dominates today.
