Final answer:
The Senate may be frustrated by obstructionist strategies like the modern filibuster and 'malign neglect' because they allow the minority to wield excessive power in halting legislation, leading to a slower legislative process and hindering the Senate's intended role to thoughtfully deliberate on bills.
Step-by-step explanation:
The Senate might be upset or bothered by "the delayer's" strategies, such as the modern filibuster, because it can significantly slow down or even halt the legislative process. This is due to the fact that a filibuster can prevent a vote on a bill unless a supermajority of 60 senators votes for cloture to end the debate. Such tactics give the Senate minority great power to obstruct legislation, leading to frustration among those who want to pass bills efficiently and effectively.
In addition to the frustration over filibusters, the Senate may also be impacted by tactics of 'malign neglect', where hearings are refused altogether as a method of obstruction. This has occurred in instances such as Supreme Court nominations and other appointments, where the Senate refuses to act not due to the quality of the nominees but as a protest against the policies of the president or due to partisan disagreements.
Therefore, the Senate's designed role to deliberate thoughtfully on legislation can sometimes lead to a political sandstorm wherein the minority can exert disproportionate influence, frustrating the majority and slowing the legislative progress, a scenario that starkly contrasts with the Founders' vision of a more mature and considerate chamber.
