Mr. Trump and his allies are aggressively attacking the players and machinery that power the left, taking a series of highly partisan official actions that, if successful, will threaten to hobble Democrats’ ability to compete in elections for years to come.

So far, the attacks have been diffuse and sometimes indiscriminate or inaccurate. But inside the administration, there are moves to coordinate and expand the assault.

Scott Walter, president of the conservative watchdog group Capital Research Center, which monitors liberal money in politics, recently briefed senior White House officials on a range of donors, nonprofit groups and fund-raising techniques. The White House group is said to be exploring what more can be done within the law.
