In most cases, only candidates who received more than 5 percent of the vote in a district are reported. Other candidates are reported as a group, but only if they in aggregate received more than 5 percent of the vote. In addition, percentages for each district may not add up to 100 percent due to rounding. The term Dissenting Republican includes various breakaway factions of the Democratic-Republican party.
