Final answer:
House Representatives constantly campaign to raise public awareness and support for their re-election efforts. This is part of the strategies identified by David Mayhew, which include advertising, credit claiming, and position taking to enhance their visibility and apparent effectiveness to the electorate.
Step-by-step explanation:
The reason why House Representatives might constantly be campaigning is closely tied to the need for reelection. Politicians, including those in the House, are driven by the goal of maintaining their positions in office. David Mayhew's election connection thesis suggests that all legislative activities of members of Congress are oriented towards increasing their chances of re-election, involving strategies like advertising, credit claiming, and position taking. Advertising allows Representatives to be seen by their electorate, which includes public speeches and interviews. Credit claiming involves them in securing benefits for their constituencies, like infrastructure funds or research grants, showcasing their effectiveness as legislators. Position taking allows Representatives to align themselves with popular opinions in their districts.
Given these re-election efforts, the most accurate answer to the original question 'Why would House Representatives be constantly campaigning?' would be B) To raise public awareness and support, as the continuous campaigning efforts are largely about maintaining visibility and demonstrating their accomplishments to their constituents, thereby securing their support for future elections.
