All states have finished their official vote tallies except for West Virginia. The national totals for U.S. House by party (using the unofficial West Virginia returns, which will probably be almost exactly like the official ones) are:
Democratic 60,447,537; Republican 50,751,049; Libertarian 768,015; Green 224,919; Working Families 217,172; Conservative 207,094; Independent Parties (of Connecticut, Louisiana and Oregon) 74,672; Reform 66,579; Constitution 59,972; Independence Parties (of Minnesota and New York) 57,463; Working Class 53,102; Women’s Equality 41,317; United Utah 36,177; Legal Marijuana Now 15,791; American 15,011; Progressive 10,758; Independent American of Utah 6,686; Liberty Union 3,924; and Socialist Equality 2,213.
The Republican share of the vote, 44.67%, is its lowest share for US House since 2008, when it was 42.94%.
For accuracy, all data was checked against data in the Cook Political Report. The national totals don’t agree because the Cook Political Report, and also Ballotpedia, assign to the major parties the vote cast for minor parties that participated in fusion. BAN disagrees with this approach because if the voter chooses to vote for a minor party, it seems that voter’s vote should be recorded for the party that the voter actually chose.
In the comments at BAN Mark Rosenthal writes
In a separate article BAN has a partial breakdown for US Senate as well:
In the 33 regularly-scheduled U.S. Senate elections held last month, the total for all Democrats was 50,770,269; for Republicans, 32,803,554.
These totals do not include votes cast for minor parties that cross-endorsed a major party nominee. Nor do they include the votes for independent U.S. Senators Bernie Sanders and Angus King, even though some sources tend to lump their vote totals into the Democratic column, since those two Senators support the Democratic Party when the Senate elects its leadership.
The main reason the Democratic margin is so huge is that in California, no one was permitted to vote for anyone for U.S. Senate except a Democrat. So the Democrats piled up 11,113,364 votes for U.S. Senate in California, with zero votes for anyone else.
This California anomaly was due to the fact that under the Top Two system two Democrats advanced from the primary leaving no choices for any other party on the general election ballot. However, even if California votes are excluded completely, the total for the Democrats is well ahead of the Republican total for US Senate, much as with US House.
In BAN comments William T. Forrest asks:
Do you have a breakdown of all the minor parties for the Senate?
Richard Winger replies:
The US Senate breakdown by party will be in the Jan. 1 2019 issue of Ballot Access News (paper), by state. So will the US House votes, by party and by state. It’s only $18 for 12 issues per year.
