The Republican plan to destroy Donald Trump
Real-estate mogul Donald Trump's Republican rivals aren't quite sure what they should do to defeat him.
The reality-television star has defied all of the conventional rules of political discourse.
Gaffes, all-out assaults on his opponents and the media, and supposedly offensive statements have done little to slow him down. Poll after poll has shown him leading the GOP primary by wide margins.
According to a Tuesday report by Bloomberg Politics' Mark Halperin, Republican strategists have settled on "four distinct but overlapping" ways of reframing Trump's candidacy to finally make him unpalatable to the party's voters.
1. "Trump can't be trusted because he is an egomaniac with a bad character."
According to Halperin, this line of attack includes a wide range of hits against Trump, including his two divorces, blotches in his business record, his casual statements about his own faith, and even "his compulsion to name things after himself."
Trump has aggressively responded to some of these criticisms in the past, including going nuclear on retired neurosurgeon Ben Carson, who ranks second behind Trump in Republican primary polls, after Carson took at slight jab at Trump's religiosity relative to his own.
Trump has also insisted that his business record has few, if any, stumbles and said his businesses' bankruptcies were just taking advantage of US bankruptcy laws.
2. "Trump is a liberal and unprincipled."
Trump, a former Democrat, has given plenty of money to his former party over the years. He has also changed his position on abortion and backed more liberal-oriented policies in the past.
Republican rivals like former Gov. Jeb Bush of Florida and Sen. Rand Paul of Kentucky have already sought to hit Trump with this line of attack.
Trump has responded by saying he gave money to Democrats to buy their support for his business ventures, by pointing to former President Ronald Reagan's own Democratic past, and by saying it's reasonable for people to change their opinions on some issues over years or even decades.
3. "Trump is not close to being fit to be a serious president or commander-in-chief."
Halperin wrote that this anti-Trump framing could bash the Republican front-runner for his vague policy statements and the recent foreign-policy interview in which he said it was not yet important for him to know the leaders of major terrorist organizations or the difference between the groups Hezbollah and Hamas.
Trump called those "gotcha" questions.
4. "Trump is a politician, not a businessman/outsider."
This line of attack would ding Trump for working within the political system for years, such as dealing with lobbyists and giving generously to various politicians. Trump, however, embraces this aspect of his past and frequently brags at campaign rallies that he used to buy and sell politicians to boost his business empire.
The second major prime-time Republican debate is Wednesday night. At least one of the 10 other candidates on stage will probably seek to take Trump down a notch by using one or more of these strategies.
