State lawmakers will have one shot to revive a bill that would keep tuition increases to a minimum when the General Assembly meets in a special session Tuesday.

It was passed by the state legislature last spring, but Ehrlich vetoed it in May. State law requires the body to review all vetoes when it next convenes.

Ehrlich (R) has spent time lobbying key Democrats to block votes to override, The Washington Post reported, and some lawmakers likely won’t even be able to attend the last-minute session falling only three days after Christmas.

An override requires the votes of 85 delegates and 29 senators — the bill passed in the House with 80 votes and in the Senate with 30.

But Student Government Association President Aaron Kraus said he met to discuss the bill with House Speaker Michael Busch (D-Anne Arundel) and other key delegates and senators who are urging the override and can “exert political pressure,” Kraus said.

Kraus, who has been lobbying for the needed votes since the summer, said he is hopeful but not confident the bill will get enough support. The vote will be partisan, and with some Democrats absent and others changing their votes, Ehrlich could likely keep the bill in the trash, Kraus said.

“In a regular session, I think we’d be in good shape to get those votes,” Busch told The Post. “But the special session has created a whole new dynamic.” Busch did not return calls for comment.

The Board of Regents, the governing body of the University System of Maryland, has been awaiting Ehrlich’s budget to set next fall’s tuition, and system Chancellor Brit Kirwan previously told The Diamondback that with $35 million more in its budget, the regents could keep next fall’s tuition increase to 5 percent. Kirwan could not be reached for additional comment.

But earlier this month, Regent Jim Rosapepe said the override was viewed as another opportunity to quell tuition increases if the budget numbers are not as high as the regents are hoping for. Ehrlich has pledged additional money for higher education in the upcoming budget, though he has not specified the amount.

“For us, this is a crucial opportunity,” Regent Joe Tydings (D) told The Post. “My feeling is that public higher education is facing an enormous risk if the governor’s veto is not overridden.”
