The McGovern-Fraser Commission issued a set of recommendations that the two parties adopted before the 1972 election. What emerged was a system of binding presidential primaries. Beginning in 1972, the vast majority of the delegates to both the Democratic and Republican conventions would be elected in state-level primaries and caucuses. Delegates would be preselected by the candidates themselves to ensure their loyalty. This meant that for the first time, the people who chose the parties' presidential candidates would be neither beholden to party leaders nor free to make backroom deals at the convention; rather, they would faithfully reflect the will of their state's primary voters. There were differences between the parties, such as the Democrats' adoption of proportional rules in many states and mechanisms to enhance the representation of women and minorities. But in adopting binding primaries, both parties substantially loosened their leaders' grip over the candidate selection process--opening it up to voters instead.
