With Republicans on the cusp of nominating for president the favorite son of white supremacists, who admires Vladimir Putin and retweets with approval the wisdom of Benito Mussolini, Democrats are within reach of achieving sweeping victories at all levels of national politics.

Trump inspires widespread media malpractice — seemingly no matter what the business mogul says, it has no effect on his candidacy. In fact, what he says will have two game-changing effects if he wins the Republican nomination.

The first is revealed by the CNN/ORC survey released on Super Tuesday, which is consistent with other polling, showing that Hillary Clinton Hillary Diane Rodham ClintonHillicon Valley: FBI chief says Russia is trying to interfere in election to undermine Biden | Treasury Dept. sanctions Iranian government-backed hackers The Hill's Campaign Report: Arizona shifts towards Biden | Biden prepares for drive-in town hall | New Biden ad targets Latino voters FBI chief says Russia is trying to interfere in election to undermine Biden MORE would defeat Trump in a general election by a large margin and Bernie Sanders Bernie SandersMcConnell accuses Democrats of sowing division by 'downplaying progress' on election security The Hill's Campaign Report: Arizona shifts towards Biden | Biden prepares for drive-in town hall | New Biden ad targets Latino voters Why Democrats must confront extreme left wing incitement to violence MORE would defeat Trump by an even larger margin.

The second effect is that a Trump nomination would cause an implosion of the Republican establishment and a conservative movement that would force every GOP candidate at every level to support or repudiate every controversial and crazy statement the celebrity billionaire makes and the media megaphones.

This “Trump effect” is already being exploited by Reid, one of the smartest political strategists and legislative tacticians in the modern Senate. He steered his party to successfully taking control of the upper chamber in 2006 and maintained Democratic control until 2014. He has worked assiduously to assemble a strong group of candidates for the 2016 elections, a cycle that already favors Democrats because of the large number of vulnerable Senate Republican incumbents seeking reelection.

If Trump is nominated, Clinton or Sanders and Democrats running for House and Senate seats will be gleefully running campaign ads against him that quote his Republican opponents for the nomination, GOP leaders in Congress and prominent conservative voices attacking him in vicious and strident terms.

Reid and House Minority Leader Nancy Pelosi will have a field day injecting repellent Trump statements into C-SPAN televised floor debates and using them aggressively to raise funds and win votes for their House and Senate candidates against vulnerable GOP opponents. Democratic challengers will wield like a whip every Trump statement in campaign ads, stump speeches and local debates and force their GOP opponents to defend or disown them.

This Trump effect will be devastating to Republicans at all levels and particularly devastating to GOP Senate candidates running in blue, purple and moderately conservative states. If Republican candidates defend Trump statements, they will lose substantial support from moderate, independent and swing voters. If they disown them, however, they will infuriate Trump supporters, many of whom are already hostile to the Washington establishment, including the -GOP-controlled Congress.

As Trump lives by the sword of media saturation, GOP candidates will politically die by that sword. The Trump effect will be magnified every time the media hypes Trump’s bigoted or repellent statements or interviews another self-described victim of his so-called university or various bankrupted companies, as well as every time it asks Republican candidates to comment on Trump statements or Democratic attacks against them.

Several generations of Republicans have sowed the seeds of the current GOP crack-up. They employed various forms of dog-whistle attacks against Democrats and liberals. In Trump, the GOP is now dominated and branded by a dog whistle that everyone can hear, and it is ugly to behold and dangerous to all Republicans in contested races.

Harry Reid is playing this GOP crack-up like Jascha Heifetz playing a Stradivarius at Carnegie Hall. He’s within reach of having the last laugh — courtesy of Trump — of Democrats regaining control of the Senate.
