Politico is running a piece called “99 Ways to Fix American Elections,” with brief suggestions from 99 commentators. One of the most original and intriguing comes from Elaine Kamarck, of the Brookings Institution:

In our constitutional system, presidents don’t govern on their own; they share power with peers in other elected offices at the state and federal level. These people—the elected governors, representatives and senators—are well-equipped to evaluate who has the skill and temperament to govern. And unlike the president, they are directly elected by the people. We should let the representatives in Congress and the governors of each state review their respective party’s presidential candidates and give them a vote of confidence or no-confidence before presidential candidates face the primary voters. This reform would constitute a small check on the chance that a corrupt person with demagogic tendencies would win a nomination and become president.
