voters fears.
civic duty.

Explanation:

• For the first question: In the early days of the United States, presidential candidates were chosen by congressional caucus. A congressional caucus was a meeting of members of Congress from the same party to select candidates. Lotteries were not used. Conventions became more prominent later. State legislatures and governors were not the original method for choosing presidential candidates.
• For the second question: Studies on political advertisements have shown that a significant number of them emphasize voters' fears. Advertisers often use fear - based appeals (such as fear of economic decline, security threats etc.) to influence voters. While positive emotions, civic duty, nonpartisan cooperation, and candidates' personal qualities may also be used, the largest number emphasizes voters' fears.

Answer:

• First question: congressional caucus.
• Second question: voters’ fears.
