An Associated Press review shows that the 2016 presidential race has already collected roughly $377 million from donors.

The first peek behind the fundraising curtain comes by midnight Wednesday, July 15, when most candidates must file their initial reports to federal regulators.

Those documents will include the names of everyone who gave at least $200, according to the AP. The maximum contribution for the primary is $2,700. The Federal Election Commission reports also will provide details about spending.

Many super PACs, which do not have contribution limits, file reports in late July.

Ahead of the deadlines, many candidates and their supportive groups have publicized fundraising totals.

Those numbers show that about half the money disclosed so far will benefit just two of the 22 presidential hopefuls, Democrat Hillary Rodham Clinton and Republican Jeb Bush.
