Answer:
The President is the one who is most likely to follow opinion polls when making government decisions, given that it is a one-man and clearly personalist position, which means that, in case of making decisions that are contrary to the majority opinions, it will impact decisively in its political image in the face of society. On the other hand, both the Senate and the House of Representatives are plural organisms, with which their members are less individualizable and, therefore, are less exposed to public opinion.
