What is one reason for the continued success of democrats in electing their candidates to office?

Democrats encourage the disadvantaged population (who are often on welfare) to get out to vote, even supplying rides to voting stations.

One of the ways that the democrats continue to win would be that they always add attractive candidates to their list continuously. This helped seal their presence in the population by the public a very good way to identify the parties by first being able to identify and love the candidates.
