House Speaker John Boehner has helped raise more than $43 million for accounts under his direct control and tens of millions more to help Republican allies.

The Ohio lawmaker accounts for about one-fifth of the cash collected by House Republicans’ campaign arm, the National Republican Congressional Committee.

Boehner has written almost $18 million in cheques to the group, which has raised $101 million this campaign cycle.

In August, Boehner plans on a 14-state bus tour to help the GOP hold the majority in the House, appearing at fundraisers for candidates. By the time Boehner returns to Washington, he will have traveled 6,000 miles and appeared at campaign events for 20 Republicans candidates.

Boehner’s draw and his fundraising skills will ensure that he will lead the GOP as long as he wants.

He “is probably the more important Republican in America today,” said North Dakota Gov. Jack Dalrymple as donors crowded to spend an August Friday night with the Ohio Republican.

Boehner’s fundraising footprint raises tens of millions through fundraising letters, automated phone calls and emails that have the speaker’s signature.

The National Republican Congressional Committee officials declined to detail how much Boehner-backed fundraising pitches collect for them. But committee aides praise Boehner’s cooperation.

“Speaker Boehner is a leader in every sense of the word,” committee spokeswoman Andrea Bozek said. “When it comes to growing our majority, he sets an example for the rest of the team.”

Republican operatives are looking around for the next prodigious fundraiser as Boehner considers retirement in coming years.

Boehner is just one of three elected officials who have moved more than $1 million directly to the committee. Former National Republican Congressional Committee chief Jeb Hensarling has moved $2.1 million from his campaign account. And Rep. Paul Ryan has moved almost $1.5 million from his House re-election committee to the party panel.
