Joni Ernst sided with the majority of Republicans on 863 of 871 votes where their party took a clear position, breaking ranks 8 times.
Counts Yea and Nay only. “Present” takes no side, so counting it as breaking ranks would penalize something that isn't. Roll calls where the member's party split evenly are excluded — there is no majority to agree with. This measures voting alongside one's party, which is not the same as ideology, and it is not comparable to DW-NOMINATE. See the methodology.
