Anybody notice that CNN is giving Nader a sympathy percentage point in their final tally of results?

The exact stats are:

But CNN presents them rounded as:

If Nader's 0.35% rounds to 1%, why doesn't Bush's 51.34% round to 52%? Did somebody make .345 the mathematically accepted cutoff point for rounding-up while I wasn't paying attention?

PS: Yes, I know this isn't a big deal. I'm taking it easy this week. But a bear has to stay in practice...
