A super PAC has raised $4 million and has collected 200,000 signatures for Dr. Ben Carson’s candidacy for the Republican presidential nomination in 2016 — but he hasn’t yet been persuaded to run.

John Philip Sousa IV, national chairman for the PAC, National Draft Ben Carson for President Committee, says members are pushing the retired physician on a daily basis, sending him petition drive updates, “clamorings” to run and more, reports Fox News, and the group believes that a Carson campaign could change the country and its politics.

Sousa, the great-grandson of famed late American composer John Philip Sousa, said his group likes Carson because he “doesn’t whine like some other Republicans. He brings a solution to the table.”

The fundraising numbers are so far competitive with those coming in for other potential candidates, reports Fox. For example, Kentucky Republican Sen. Rand Paul has raised about $4.7 million.

But unlike Paul, Carson has never held political office, and is not expected to make a decision if he wants to run until next year. He told “The Steve Malzberg Show” on Newsmax TV earlier this year that only extraordinary circumstances could drive him to throw his hat in the ring.
