User:SuperWIKI/sandbox/State deans (6)

For senators and representatives who represented defunct parties or switched parties intra-term, only their latest party while in office is reflected. Most states, due to not having long-running deans until the 1900s, have tables only starting from that decade.

Guidelines[edit]

Checklist[edit]

Check all dates (Congress sessions, individual terms, deanships, ayds)
Check seniority (shared seniority, alphabetical precedence, combined House and Senate tenures, causes of departure)
Check numbered seniority (if death caused seniority to go up independent of list number)

Seniority criteria[edit]

Number of consecutive terms (for speed, use seniority date)
Number of past, non-consecutive terms
Alphabetical order of surname (if more than two people fulfill same seniority after above criteria, use individual with earliest surname in alphabet)
For Representatives elected to fill vacancy, seniority is calculated from date of special election. Column-wise (Congress), at-large representatives use the date they were sworn in.
