The source familiar said the decision to delay the vote was made because of a host of outstanding questions, including how each election would be administered and the feasibility of each primary day.
The source added Democrats want to make sure the focus stays in the midterms and not the 2024 nominating process.

Democratic Party officials earlier this year approved a plan which requires any state that wants to hold a nominating contest before the first Tuesday in March — including the traditional early four of Iowa, New Hampshire, Nevada and South Carolina — to apply for permission.
Last month, Colorado, Connecticut, Delaware, Georgia, Illinois, Iowa, Maryland, Michigan, Minnesota, Nevada, New Hampshire, New Jersey, Oklahoma, Puerto Rico, South Carolina, Texas and Washington made presentations to the Rules and Bylaws Committee detailing why they should be among the first states to hold presidential nominating contests in the next presidential election.
At the time of the presentations, the focus was especially on Iowa, which was proposing dramatic changes to its complicated system as it aimed to maintain its “first in the nation” status in the face of criticism of the caucus process and of the state’s lack of diversity and competitiveness at the presidential level.
Because the Democratic Party is aiming to have every region of the country represented among the early group of states, and the positions of New Hampshire, Nevada and South Carolina are generally considered to be secure, it’s expected there will be fierce competition among other Midwestern states to be the alternative to Iowa.
Minnesota, Michigan and Illinois are jockeying for the spot, but all three bids have potential problems of their own.
During the presentations, Iowa’s proposal called for several simplifications to the caucus process.
