Which of the following describes a veto? A. A tactic for delaying or obstructing legislation by making long speeches B. A tactic for winning an election without winning a majority of the vote C.

A veto is like the ultimate "pause button" in government; it's a power held by executives, like the president or governors, to reject a bill proposed by the legislature. This means that even if the majority supports a piece of legislation, the executive can say "nope," effectively stopping it in its tracks. It's a crucial tool for maintaining checks and balances, ensuring that laws meet certain standards before becoming official. In the real world, an example of a veto in action was President Barack Obama’s rejection of the Keystone XL Pipeline project in 2015. This decision, based on environmental concerns, showcased how a single veto can shape policy and public debate. Here, the executive's influence directly impacted national priorities and dialogue surrounding energy and climate change.
