Sodium is often blamed for boosting blood pressure while potassium is praised for keeping it in check. It really doesn't make sense to look at these two minerals separately, though, since they work in tandem throughout the body. The ratio of sodium to potassium in the diet may be more important than the amount of either one alone.
