As of: 98% reporting in both districts; latest county vote timestamps 2026-11-10 02:06 UTC (MT-1) and 2026-11-09 23:31 UTC (MT-2), i.e. Nov 9 9:06 pm / 6:31 pm ET; extracted 2026-11-10 02:20 UTC (Nov 9, 9:20 pm ET).

Validation (sum of county rows vs statewide totals)

Year	Column	Our sum	Reference	Diff
2022	D	158,745	158,745 (FEC)	0
2022	R	245,081	245,081	0
2022	Other	59,806	59,806	0
2026	D	203,657	202,412 (Nov 9 6:10 pm ET aggregate)	+1,245
2026	R	250,690	249,985	+705
2026	Other	28,677	(not reported)	—

2022 matches exactly. In 2026 our totals are a little higher than the national aggregate. Counties in both districts reported new votes after 6:10 pm ET (23:10 UTC), so this is a newer count, not a missed district.

Districts without a D or R candidate

2022: none. MT-1 had Tranel (D), Zinke (R), Lamb (L). MT-2 had Ronning (D), Rosendale (R), Buchanan (I), Rankin (L).

Caveats

2026 numbers are unofficial (about 98% reporting) and will change before the state canvass.
o22 = Libertarian and Independent candidates as printed in the canvass (no write-ins listed). o26 = the minor candidates CNN reports. Write-ins are not included.
In 2022, Gary Buchanan (Independent, MT-2) received 47,195 votes. That is most of o22 in MT-2 counties, so compare o across years with care.
