Maryland Gov. Larry Hogan raised more than $1.2 million between April 10 and May 15, amassing more money in 35 days than some of his Democratic challengers have done since they launched their campaigns last year.

In a memo obtained by The Washington Post, Hogan’s campaign chairman said the Republican governor and Lt. Gov. Boyd K. Rutherford, who do not have primary opponents, have more than $9 million cash on hand for their reelection bid.

“Despite the fact that we were legally prohibited from fundraising during the three-month legislative session, Hogan for Governor remains in a very strong financial position,” Tom Kelso wrote. “We exceeded our goals for the period, and, with your help, expect to continue fundraising at a similar or greater pace throughout the balance of the campaign.”

With $9 million, Hogan and Rutherford have nearly twice as much cash on hand as their predecessors, Gov. Martin O’Malley and Lt. Gov. Anthony G. Brown (D) had in their accounts eight years ago.

Kelso said that nearly 70 percent of the donations came from smaller-scale donors, who gave $250 or less.

New campaign finance reports are due to the state Board of Election by Tuesday night.

The reports, which will detail how much candidates raised Jan. 11 through May 15, will show how the seven major candidates vying to unseat Hogan are faring five weeks before the June 26 primary. The last filing deadline is June 15.

In reports filed in January, Kevin Kamenetz, who died this month, had a $2 million war chest, the largest among the Democratic candidates. Board of elections officials have not said what will happen to the money in Kamenetz’s account and the joint account he shared with his running mate, Valerie Ervin. Ervin announced last week that she would replace Kamenetz at the top of their ticket and that Marisol Johnson would be her running mate.

Former NAACP president Ben Jealous and Baltimore attorney James L. Shea followed close behind Kamenetz last year, raising $1.5 million each.

Kelso said Hogan’s “flush bank account and determination to continue aggressively fundraising in the future months” will allow Hogan to outspend his Democratic opponent in the fall “to effectively communicate his record.”
