NBC News: “Some pundits and voters say one candidate — former Vice President Joe Biden — is the most electable, so they tell pollsters they want Biden, which produces media coverage that reinforces the idea that Biden is most electable, which then filters back down to voters concerned about ‘electability.'”

Wall Street Journal: “As the first round of Democratic debates approaches, presidential candidates polling around 1% look for a breakout moment.”

E.J. Dionne Jr.: “If you’re in a lower tier, you have to decide on the one thing you really want voters to know about you or the issue you want to push to the fore.”

“For some candidates, that’s relatively easy. Washington Gov. Jay Inslee will be talking climate change, while Julián Castro and Beto O’Rourke have been more upfront than anyone on immigration.”

Leonard Steinhorn: “Historians and journalists have scoured our recent past looking for precursors to the white working class grievance that fuels the presidency of Donald Trump. Surprisingly, none has explored a forgotten riot that may hold the answer.”

“It was 40 years ago this week when white-working-class anger spilled over in the unlikeliest of places: the streets of the Philadelphia suburb of Levittown, long considered a symbol of the American Dream. What happened during the Levittown gas riots — and why — offers much insight into Trump’s appeal to his base.”

A new Associated Press-NORC poll finds just 22% of Democrats registered to vote say they know a lot about the presidential candidates’ positions, while 62% say they know a little.

And only 35% say they’re paying close attention to the campaign, with almost two-thirds saying they’re paying some or no attention.
