Maryland Lt. Gov. Anthony G. Brown (D) and Howard County Executive Ken Ulman (D) plan to hold their first major fundraiser next week as a gubernatorial ticket, underscoring one of the advantages of their early entry in the 2014 race.

Aides are billing next Thursday’s event at Baltimore's Museum of Industry as one of the biggest to date in Brown’s bid to succeed Gov. Martin O’Malley (D). Tickets start at $250 a person and range up to $4,000 for “VIP” access.

In the early stages of the Democratic primary, Brown is playing catch-up in the fundraising department. As of January, Attorney General Douglas F. Gansler (D), who has yet to formally announce his gubernatorial bid, had $5.2 million in the bank. Brown had $1.6 million on hand.

Ulman, who was unveiled May 3 as Brown’s lieutenant governor candidate, had $2.1 million in the bank as of January.

Ulman appeared with Brown at a fundraiser in Potomac two days after he was announced as Brown’s running mate. But next week’s event will be the first time the two men’s fundraising operations have worked together in a focused way, said Justin Schall, Brown’s campaign manager.

According to the invitation, those attending can donate to either Brown or Ulman’s campaign account, both of which will remain open.

In advance of the June 2014 primary, Maryland’s fundraising rules provide more leeway to Ulman’s fundraising efforts than those of Gansler, Brown and Del. Heather R. Mizeur (D-Montgomery), who is also expected to enter the race.

During Maryland’s 90-day legislative session, which starts in January, legislators and statewide officeholders — including the lieutenant governor and attorney general — are not allowed to solicit campaign funds. The ban does not apply to county executives.

Gansler is not expected to formally announce his governor’s bid until the fall, and is unlikely to designate a running mate until after doing so. Mizeur is expected to announce her bid in coming months.
