CAL MATTERS--Ballots are still being counted, but last week’s election is already offering good news for Democrats hoping to take back the House of Representatives in November.
Not only did the party steer clear of its dreaded “shutout scenario,” in which an oversupply of candidates in some of the state’s most competitive races threatened to divide up the Democratic vote, leaving only Republicans to advance to the general election. The preliminary count also suggests that primary voters in certain high profile districts are much more inclined toward Democrats than they were in 2014.
That may or may not foretell a “blue wave” in California, but it does show that Republicans have their work cut out for them.
Why should the array of (mostly) leftward pointing arrows worry Republicans?
Comparing the June 2018 primary to the June primary in 2014, the share of the vote going towards Republican candidates has fallen dramatically in many of the very seats that Democrats are most hoping to flip this fall.
In the district along the border of Orange and San Diego counties represented by GOP Rep. Darrell Issa, who is retiring this year, a majority of primary voters cast their ballots for a Democrat.
A few more of the districts national Democrats have targeted are within spitting distance of a partisan break-even. In GOP Rep. Jeff Denham’s district in the Central Valley, Republicans cobbled together 52 percent of the vote (down from 59 percent in 2014). Likewise, in both Laguna Niguel and Palmdale, Rep. Mimi Walters and Rep. Steve Knight, the only Republicans running in their districts, got 52 percent of the vote as well.
That represents a big shift since 2014, the only other non-presidential election year in which a primary was held under the state’s new top-two system.
In Issa’s district, 16 candidates were vying to replace him in the lead up to June 5. The top two winners, Republican Diane Harkey and Democrat Mike Levin, won around 26 percent and 18 percent of the vote, respectively.
What would a head-to-head Harkey-Levin match-up look like without the 15 other competitors?
One way to guess is to tally up the share of the vote that went to all Republican candidates and compare it to the Democratic share. Assuming that the various supporters of Assemblyman Rocky Chávez, San Diego Supervisor Kristin Gaspar, and the other five Republicans running in that district are likely to fall behind their party’s candidate in the general election, that ought to give us a pretty good idea of what to expect in November.
And the results don’t look good for Harkey.
So far (and again, ballot are still being counted), the Republican candidates in Issa’s seat have garnered 48 percent of the vote. That’s compared to 51 percent for all the Democrats.
That’s also a steep decline from the 2014 primary share when Issa, running as the only Republican, won 61.9 percent of the vote.
Even in districts like Denham’s, Walters’, Knight’s, and Rep. Dana Rohrabacher’s, where Republicans won slim majorities of last week’s vote, those margins may be a little too close for comfort for the GOP. Republicans tend to be more reliable primary voters than Democrats and political independents, so the Republican share of the vote is likely to be lower in most districts come November.
In 2014, for example, Republican vote share between the primary and general elections declined by an average of 1.3 percentage points. That was true of all California congressional races, excluding those where one party was shut out or where a candidate ran unopposed. Looking only at the most competitive races (again, excluding shutouts), the average decline in Republican support was 3.3 percentage points between June and November.
We’ll update these stats as more ballots are counted.
