Clinton Digs In as Trump Moves On

As Mrs. Clinton and Mr. Trump aim to clinch their parties’ nominations, the former secretary of state is poised to start the general-election campaign with a far more sophisticated operation in key swing states than the businessman.

“It unequivocally is helpful for a campaign that spent a year-plus working in Iowa to keep some people in play,” said David Oman, a former Iowa state GOP co-chairman and senior political adviser to former Florida Gov. Jeb Bush, who quit the race last month. “It would be a mistake to let people go…and then have to put the team back together again to marshal a general-election campaign.”

Mr. Trump has largely eschewed implementing a traditional ground game, instead relying on large rallies and his star power to turn out voters. As a consequence, strategists in Iowa and New Hampshire say there’s little left of his already-sparse operations in the states.
