Donald Trump’s Presidential Run Began in an Effort to Gain Stature

Repeatedly underestimated as a court jester or silly showman, Mr. Trump muscled his way into the Republican elite by force of will. He badgered a skittish Mitt Romney into accepting his endorsement on national television, and became a celebrity fixture at conservative gatherings. He abandoned his tightfisted inclinations and cut five- and six-figure checks in a bid for clout as a political donor. He courted conservative media leaders as deftly as he had the New York tabloids.

.. “I realized that unless I actually ran, I wouldn’t be taken seriously,”

.. he tested the themes that would one day frame his presidential campaign: American economic decline, and the weakness and cluelessness of politicians in Washington.

.. Over the next few months, Mr. Trump met quietly with Republican pollsters who tested a political message and gauged his image across the country

.. Roger Stone, a longtime Trump adviser, wrote a column on his website envisioning a Trump candidacy steamrolling to the nomination, powered by wall-to-wall media attention.

.. While he saw himself as an important spokesman on economic issues and a credible champion for the party, the Romney campaign viewed him as an unpredictable attention-seeker with no real political foundation.

.. Mr. Trump was drawing presidential candidates seeking his support to his Fifth Avenue high-rise. In September 2011, Mr. Romney made the trip, entering and exiting discreetly, with no cameras on hand to capture the event.

.. Mr. Trump reached out to say he wanted to endorse Mr. Romney at a Trump property in the state. Wary of such a spectacle in a crucial state, Mr. Romney’s aides began a concerted effort to relegate Mr. Trump’s endorsement to a sideshow.

The Romney campaign conducted polling in four states that showed Mr. Trump unpopular everywhere but Nevada, and suggested to Mr. Trump that they hold an endorsement event there, far away from Florida voters

.. In an appeal to Mr. Trump’s vanity, the Romney campaign stressed that his endorsement was so vital — with such potential to ripple in the media — that it would be a mistake to dilute the impact with a question-and-answer session.

.. Mr. Obama, in a speech on Friday, said Republicans had long treated Mr. Trump’s provocations as “a hoot” — just as long as they were directed at the president.

.. Mr. Trump had struck up a friendship in 2009 with David N. Bossie, the president of the conservative group Citizens United, who met Mr. Trump through the casino magnate Steve Wynn.

.. Mr. Trump began a relationship with Reince Priebus, the Republican National Committee chairman, who was trying to rescue the party from debt.

.. In 2014, he cut a quarter-million dollar check to the Republican Governors Association, in response to a personal entreaty from the group’s chairman — Chris Christie.

.. Mr. Trump peppered Mr. Gingrich with questions about the experience of running for president, asking about how a campaign is set up, what it is like to run and what it would cost.

.. Pundits seemed unaware of the spade work he had done throughout that spring, taking a half dozen trips to early voting states of Iowa, New Hampshire and South Carolina and using forums hosted by Mr. Bossie’s group to road test a potential campaign.
