Answer:
The correct answer would be Speaker 3: I´m a longtime Republican. I don´t agree with all the party´s goals, but it represents the majority of my interests effectively.
Step-by-step explanation:
This would be the speaker who would most likely feel represented in the current U.S government, given the fact that this person is allied with the party that has control of most of the government branches at the moment and his interests are better represented as they align with those of the Republican party itself. Also, this is the only speaker, from the choices, who seems to still be involved with his party, as the others show to be more discontent, and therefore, less represented by the party that is in government at the moment.
