Final answer:
Voting for all Republicans is known as casting a 'straight ticket', which allows a voter to select all candidates from the Republican Party with a single option at the top of the ballot.
Step-by-step explanation:
If you vote for all Republicans, you would be voting a straight ticket. This means you are choosing to vote for every candidate from the Republican Party on the ballot. In some states, there is an option to select one box at the top of the ballot to vote for all candidates from one party quickly. This practice reduces ballot fatigue, ensuring that voters do not stop voting before reaching the bottom of a long ballot. However, it is noteworthy that straight-ticket voting only applies to partisan positions and does not include any non-partisan seats such as judicial ones, which might also be present on the ballot.
