The first overview would be to examine the historical parameters, then consider who best fits them. It should be born in mind that no VP candidate has ever ensured the Electoral College victory of the top of the ticket so in the end the choice may be of no consequence.
Typically, a vice-presidential candidate is chosen to complement the presidential candidate and balance out any perceived weaknesses. Some factors that might be considered when selecting a vice-presidential candidate could include:
1. Geographical balance: A candidate from a different region of the country could help broaden the appeal of the ticket.
2. Demographic balance: A candidate who represents a different demographic group, such as a woman, a person of color, or someone from a different age group, could help attract voters who might not otherwise support the ticket.
3. Policy alignment: A candidate who aligns with the presidential candidate on key policy issues could help bolster the campaign's message and attract voters who support those policies.
4. Experience: A candidate with experience in government or other relevant fields could help the presidential candidate in areas where they may be weaker.
5. Party unity: A candidate who is well-respected within the party and can help unify different factions.
