To find the probability, we need to divide the average number of people who voted in presidential elections by the average number of registered voters in the Democratic party:
$$\frac{11,800,000}{26,800,000} \approx 0.44$$
Therefore, the probability that a person selected at random from the registered Democratic voters will vote in the next election is 0.44, rounded to two decimal places.
