Marylanders are about evenly divided over an expanded gambling proposal, while majorities say they will support same-sex marriage and an immigrant tuition measure on the November ballot, according to a new poll.

The poll, by Gonzales Research & Marketing Strategies, comes just weeks before Marylanders face several far-reaching decisions on Election Day. Here are the numbers:

●Statewide, 45 percent of voters say they will vote for the expanded gambling proposal, while 46 percent say they will vote against it. Nine percent are undecided. The plan would allow a new casino in Prince George’s County and table games at Maryland’s five previously authorized slots venues.

●Fifty-one percent say they will vote to uphold the state’s same-sex marriage law, while 43 percent say they will vote against it. Six percent are undecided. The law would allow gay nuptials to begin in January.

● Fifty-eight percent say they will vote to uphold an immigrant tuition law while 34 percent say they will vote against it. Eight percent are undecided. The “Dream Act” would allow undocumented students to pay in-state college tuition rates under certain conditions, including having parents who file state tax returns.

Varying levels of African American support help explain the results, according to Gonzales.

Seventy percent of black voters support the “Dream Act,” while only 31 percent support the expanded gambling measure.

Forty-four percent of African American voters support same-sex marriage, a figure that has increased from 33 percent in a similar poll from January. Gonzales says the result suggests that public pronouncements from President Obama and others have contributed to the change.

The poll included 813 registered voters who say they are going to vote in the November election. It was conducted between Sept. 17 and Sept. 23. The margin of error is plus or minus 3.5 percentage points, according to Gonzales.
