Validation (sum of county rows vs statewide totals)

Year	Column	Our sum	Reference	Diff
2022	D	178,416	178,416 (FEC)	0
2022	R	138,201	138,201	0
2022	Other	5,032	5,050	−18
2026	D	243,467	243,467 (Nov 9 6:10 pm ET aggregate)	0
2026	R	134,966	134,966	0
2026	Other	blank	(not reported)	—

The 2022 "other" gap of 18 is write-in votes (Edward Shlikas 3, Scott Walker 15). The state reports them only statewide, not by county, so they are not in the county rows. 2022 o = Libertarian (Cody McNutt 3,074) + Non-Partisan Delaware (David Rogers 1,958).

Districts without a D or R candidate

2022: none (at-large: Blunt Rochester D, Murphy R, plus LIB and NPD).
2026: none (at-large: Sarah McBride D, Joseph Arminio R; no other ballot candidates).

Caveats

2026 o is left blank. Only the D and R nominees were on the ballot, and the ENR feed does not report write-ins. Treat it as "not reported", not as zero.
2026 is unofficial election-night/canvass data, unchanged since Nov 4.
