Our columnist Holman W. Jenkins, Jr. writes that Donald Trump “may not be a solution in himself, but an outsider at least can be an instrument to dislodge an elite and replace it, for a while, with an elite less habituated to using public power to favor and enrich itself.” Mr. Jenkins adds, “A few weeks ago Mrs. Clinton was the ‘safe hands’ candidate. If she wins, it now appears hers will be an embattled and investigated presidency from day one.”

Democratic vice presidential candidate Tim Kaine predicts that given the opportunity, Democrats will destroy the filibuster to seat their favored Supreme Court picks. A Journal editorial says that “if Republicans want to have any chance of blocking Mrs. Clinton’s nominees they’ll need to retain at least 51 Senate seats, which should get voters’ attention.”

Something else bound to get their attention: “As a parting gift to young voters, the Obama Administration last week issued a rule allowing borrowers to discharge billions of dollars in student debt,” notes a separate editorial. The Education Department has unilaterally rewritten the law and now pegs the taxpayer cost at between $9.5 billion and $21.2 billion over the next decade, but “it has repeatedly lowballed the costs of its loan-forgiveness programs,” notes the editorial board.

Speaking of young voters, marijuana is now legal in four states for recreational use. Voters in another five have a chance to legalize on Nov. 8, “but the evidence rolling in from these real-time experiments should give voters pause,” writes the editorial board. “The share of pot-related traffic deaths has roughly doubled in Washington and increased by a third in Colorado since legalization, and in the Centennial State pot is now involved in more than one of five traffic fatalities. Calls to poison control for overdoses have jumped 108% in Colorado and 68% in Washington since 2012.”

Our columnist William Galston shares the results from a new survey on immigration: “More than six in 10 (62%) white working-class Americans see immigration as a threat, compared with only 34% of whites with a college education. Black Americans are evenly divided, 46% to 46%, and a surprisingly large share of Latinos (37%) view high levels of immigration as a threat.” Mr. Galston writes that “our laws should put more emphasis on rapidly acquiring not only English-language proficiency but also basic civic competence.”
