This bill is about changing how presidential electors are chosen and how the state of Minnesota participates in the presidential election process. The key points of the bill are:

1. Nomination of Electors: The major political parties in Minnesota will nominate presidential electors and their alternates through delegate conventions organized by their state central committees. Each party will nominate one elector from each congressional district and two from the state at large. The details of these nominees and the party candidates for President and Vice President will need to be certified to the state's Secretary of State at least 71 days before the general election.

2. Canvassing Votes: The State Canvassing Board, which oversees the election process, will open and count the returns for presidential electors and declare the winners based on the highest number of votes received statewide and in each congressional district.

3. Withdrawing from the National Popular Vote Agreement: The bill will withdraw Minnesota from the National Popular Vote Interstate Compact, which is an agreement among some states to award their electoral votes to the candidate who wins the overall national popular vote, rather than the popular vote within their state alone.

4. Repeal of Existing Statutes: The existing statutes related to the state's participation in the National Popular Vote Interstate Compact are repealed, which means they are being removed from the law.

In summary, this bill changes how Minnesota handles the nomination and election of presidential electors, by reverting to electors being chosen based on state and district vote totals rather than the national popular vote, and officially withdraws the state from the National Popular Vote Agreement.
