Washington Post: “Confused and frustrated, a growing number of Democrats are blaming their own party as they seek to avert a drubbing in Tuesday’s congressional primaries here that would leave their candidates shut out of the November ballot in some races — and with a narrower path to win control of the House of Representatives.”

“Candidates are scrambling to set themselves apart, Democratic groups are urging unity to gain control of the House — and many voters are wondering how to contend with the despair they would feel if Democrats were locked out in this liberal state.”

First Read: “On the GOP side, President Trump has endorsed Republican John Cox for governor, trying to unite California Republicans around a single candidate, which could help drive turnout in the House and downballot races… In addition, House Republicans have opened an office in Southern California to spur GOP turnout in the three key House districts.”

“On the Democratic side, the DCCC has been airing TV ads both in favor of their preferred candidates in these crowded primaries (see here and here) and against Republican candidates (see here and here). And while House Democrats want two Democrats at the top of the ticket for governor – to drive Dem turnout and depress the GOP’s – gubernatorial frontrunner Gavin Newsom prefers a Republican opponent, since someone like fellow Democrat Antonio Villaraigosa represents a greater general-election threat than either of the two leading GOP candidates (Cox and Travis Allen).”

“What’s fascinating about all of these races is that they’re essentially margin-of-error contests to make the Top 2, where candidates in positions No. 2, No. 3 and even No. 4 are separated by just a handful of points in the public and private polling. All of which makes the June 5 primaries – and the strategies going into them – quite a game.”

Vox: California’s “top two” primary chaos, explained.

“Backing an effort for California to claim a bigger share of the attention from presidential candidates, Gov. Jerry Brown has signed a bill moving the state’s primary elections to early March,” the Los Angeles Times reports.

“Brown’s decision, announced without fanfare on Wednesday, means the state will hold its presidential primary on March 3, 2020. It’s a reversal from a decision he and Democratic lawmakers made in 2011 to push the state’s primary elections back until June, after years of trying — and failing — to entice major candidates to bring their campaigns to California instead of smaller, more rural states.”

The schedule change comes as Sanders has barnstormed California, not leaving the state in more than a week. Meanwhile, a recent poll found the race closing significantly. Clinton’s lead over Sanders had narrowed to just two points.”
