At least four separate organizations are seeking to drive public support for Trump and his priorities — a marked shift from the first two months of his administration, when the White House had limited outside air cover.

The immediate goal: to lean on Democratic senators in the run-up to a vote expected this week on Supreme Court nominee Neil Gorsuch. But down the road, some of the groups could end up turning their focus on lawmakers who cross Trump, including members of his own party, according to people familiar with internal discussions.

“It is something we would consider if there is clarity that a group is stymieing the agenda, whether it’s establishment types or others,” said Eric Beach, co-chairman of the pro-Trump advocacy group Great America Alliance, which has already spent $3.5 million on ads promoting the Trump administration.

Pressure could also eventually come from America First Policies, which was launched by a group of former Trump advisers in January to serve as the leading pro-Trump advocacy group. The organization has not yet turned its attention to the 2018 midterm elections, said spokeswoman Katrina Pierson.
