Shares are of the state’s total vote for president. Margin is the leader’s lead over the second-placed candidate. “Others named” lists every other candidate the figures give a line of their own.

Notes on the figures

2024 'Other candidates' includes 12,409 blank, void, over- or under-vote or 'none of these candidates' ballots, which the source reports as lines of their own.
2020 'Other candidates' includes 1,886 blank, void, over- or under-vote or 'none of these candidates' ballots, which the source reports as lines of their own.
2016 The MIT Election Lab file gives Evan McMullin 60,748 votes; the FEC's official results give 46,476. This site shows the FEC figure.
2016 The MIT Election Lab file has no figure for Jill Stein; the FEC's official results give 8,496 votes, which is the figure shown here.
2016 The MIT figure for Evan McMullin (60,748) equals the FEC's figures for McMullin (46,476), Jill Stein (8,496), Darrell Castle (4,403) and Rocky De La Fuente (1,373) added together, and the MIT file's 2,356 for Castle is the FEC's figure for Scott Copeland. Castle, Copeland and De La Fuente are each under 1%, so they are counted in 'Other candidates'.
2016 The MIT file and the FEC give the same state total; 'Other candidates' is that total minus the candidates shown.
2012 The source reports 6,901 votes under the label 'Independent' on one line with no candidate name, so the people they went to cannot be shown separately; they are counted in 'Other candidates'.
1992 The MIT Election Lab file gives Bo Gritz 10,894 votes; the FEC's official results give 10,281. This site shows the FEC figure.
1992 The MIT figure for Bo Gritz equals the FEC's figures for Gritz (10,281) and Lenora Fulani (613) added together.
1992 The state total (482,142) is the FEC's official total; the MIT file's total is 482,114. 'Other candidates' is that total minus the figures shown.
1920 The official table prints no state total here; the total is the sum of the tickets it lists.
1920 The official table notes: The summary table prints 32 in the Watkins (Prohibition) column on Idaho's line; the Idaho state page (PDF page 3) lists only Republican, Democratic and Socialist (38). The 32 is kept as printed in the summary (the column then adds to its printed total).
1896 The official table prints no state total here; the total is the sum of the tickets it lists.
1892 The Democrats ran no electors here in 1892 and backed Weaver's Populist ticket, so Cleveland is not listed (World Almanac 1894, p. 375).
1892 The official table prints no state total here; the total is the sum of the tickets it lists.
