McIntosh said she sometimes asks the governor for tickets; other tickets were unsolicited. She said she's never felt any pressure to vote a certain way as a payback.

"I'm a huge Ravens fan," she said. "On one or two occasions, I brought my mother, who loves the games. I don't see it as a litmus test about the way people vote. I see it as watching the Ravens."

Even so, records show O'Malley generally invites fellow Democrats and their relatives and backers.

For instance, at the Nov. 20 game against the Cincinnati Bengals, Mitchell and Clippinger were joined by Council President Young; first lady Katie O'Malley; David Dixon, an O'Malley campaign strategist; O'Malley's chief legislative officer, Joe Bryce; Teddy Downey, the stepson of Carol Browner, the former director of the White House Office of Energy and Climate Change Policy; and Lonnie Robbins, the chief administrative officer for Howard County.

Mitchell said he took his daughter to the game, and she appreciated the opportunity to meet the governor. He remembers the game well because Katie O'Malley scolded him for spilling popcorn and not picking it up. But Mitchell was quick to divert the blame from himself, he said.

"I blamed it on Jack," Mitchell said, referring to Young.

Only one Republican lawmaker, Sen. Richard F. Colburn of the Eastern Shore, was a guest at a Ravens game last season. He declined to be interviewed.

"We work with him on issues with the Eastern Shore," Abbruzzese said. "It's proof it's bipartisan."

The Ravens tickets are in demand, with the governor's office receiving dozens of emails inquiring about getting them, documents show.

Once, when former Baltimore County Executive James T. Smith Jr. asked about getting access to a box for charity, he was rebuffed.

"Given the limited number of tickets and the high demand, we've only donated tickets for charity twice over the last four years," wrote Matthew Gallagher, O'Malley's chief of staff, in an April 6 email to Smith.

"The Steelers tickers are usually in particularly high demand given the number of O'Malley family members that make the trip down from Pennsylvania."

In responding to the public information request, the governor's office also included a list of attendees at O'Malley's box at Oriole Park at Camden Yards — as well as a breakdown by category. O'Malley uses that box 37 percent of the time for nonprofits and charities; 36 percent of the time for government relations; and 22 percent of the time for state government uses, such as business outreach and staff appreciation, his office said. Three games were unused last season because of rainouts or time changes.

O'Malley hosted business leaders on Opening Day, Katie O'Malley used the box once and Plaxen's law firm used the box on two occasions. Plaxen says his firm auctioned off the tickets for charity.

The governor invited representatives of the HBO show "Game Change," which was filming in Baltimore, to the April 24 game against the Yankees, and rewarded his staff with tickets to an April game against Boston.

The South Baltimore Learning Center got to see the Royals in May; Healthcare for the Homeless was invited to a Blue Jays game in June.

Abbruzzese said O'Malley has never asked a lawmaker to return a ticket.

"We've never done that, but I'm sure there's something you could do to get you uninvited," he said. "It's to establish personal relationships. It's not a heavy-handed approach."

Mitchell said he has never been asked to return tickets — even when he opposed then-Mayor O'Malley on the budget and financing for the Hilton hotel.

"I was one of the few that voted against the budget on the City Council and I was able to go to a baseball game and didn't get stuck in left field," Mitchell said. "I voted against the hotel and got invited to the Ravens game. There's never been a quid pro quo. Absolutely not."
