At the [[1860 Republican National Convention]], Collamer received the [[favorite son]] votes of Vermont's delegates and withdrew after the first ballot.<ref>The Vermonter magazine, [https://books.google.com/books?id=wZk6AQAAMAAJ&dq=%22jacob+collamer%22+1860+convention+votes+president&pg=PA5 Incidents in the Life of Lincoln], January 1909, page 5</ref>  Reelected to the Senate in 1861, he served until his death.<ref>William Lloyd Garrison, [https://books.google.com/books?id=v5aZrAuKt0wC&dq=%22jacob+collamer%22+reelected+senate+1861&pg=PA397 The Letters of William Lloyd Garrison], 1976, page 397</ref>

In 1861, Collamer authored the bill to invest the President with new war powers and give Congressional approval to the war measures that [[Abraham Lincoln]] had taken under his own authority at the start of his administration.<ref>Jacob G. Ullery, [https://books.google.com/books?id=Nvg_AAAAYAAJ&q=collamer&pg=PA224 Men of Vermont Illustrated], 1894, pages 121-124</ref>

Collamer was the lead senator of the nine Republicans who visited Lincoln in 1862 to argue for change in the composition of his cabinet by persuading him to replace his [[US Secretary of State|Secretary of State]], [[William Henry Seward]].<ref>Chester G. Hearn, [https://books.google.com/books?id=cmZkBkmBc7wC&dq=%22jacob+collamer%22+seward+chase+lincoln+meeting+cabinet&pg=PA141 Lincoln, the Cabinet, and the Generals], 2010, pages 139-143</ref> Having been encouraged to confront Lincoln by claims of cabinet disharmony from Lincoln's [[US Secretary of the Treasury|Secretary of the Treasury]], [[Salmon P. Chase]], the senators changed their minds during the meeting after Chase was maneuvered by Lincoln into backtracking on his initial argument.<ref>{{cite book|url=https://books.google.com/books?id=cmZkBkmBc7wC&q=%22jacob+collamer%22+seward+chase+lincoln+meeting+cabinet&pg=PA141|title=Lincoln, the Cabinet, and the Generals|first=Chester G.|last=Hearn|date=28 March 2018|publisher=LSU Press|isbn=9780807137338|via=Google Books}}</ref>

Again a member of the majority once the [[Democratic Party (United States)|Democrats]] from the southern states left the Senate during the war, Collamer was Chairman of the Committee on the Post Office and Post Roads ([[37th United States Congress|Thirty-seventh]] to [[39th United States Congress|Thirty-ninth Congresses]]) and the Committee on the Library ([[38th United States Congress|Thirty-eighth]] and Thirty-ninth Congresses).{{sfn|Chairmen of Senate Standing Committees, 1789-present}}

After the war, Collamer opposed the [[Reconstruction era of the United States|Reconstruction]] of plans of Presidents Lincoln and [[Andrew Johnson]] and was an advocate of Congressional control over the process of readmitting former [[Confederate States of America|Confederate]] states to the Union.<ref name="auto"/>
