Former Maryland Del. Tiffany T. Alston (D-Prince George’s) launched a comeback bid Tuesday night, arriving at the State Board of Elections to file for her old seat just 20 minutes before the 9 p.m. deadline.

“There’s a lot of unfinished business that needs to be addressed in the 24th District,” Alston said after filling out the necessary paperwork. She added that many of her constituents have urged her to run again.

Alston was removed from the House in 2012 following a trial in which she was convicted of theft and misconduct in office by an Anne Arundel County jury. She was originally charged with stealing $800 from the General Assembly to pay an employee of her law firm, which she vigorously denied. Alston’s record has now been wiped clean as a result of a plea deal and successful completion of a sentence that included restitution and community service.

She joins a field of 10 Democratic candidates seeking the three seats representing District 24.

All three incumbents are running, including Dels. Carolyn J.B. Howard (D-Prince George’s), Michael L. Vaughn (D-Prince George’s) and Darren M. Swain (D-Prince George’s), whom Gov. Martin O’Malley (D) appointed to fill the remainder of Alston’s term.

The race also includes Gregory A. Hall, who was originally nominated by the Prince George’s Democratic Central Committee to take over Alston’s seat. O’Malley, however, refused to appoint Hall, who had been jailed two decades earlier on drug and murder charges, the latter of which were dropped.

Alston said her legal saga “may be a factor” in the race, but she added that having “survived the justice system” makes her more empathetic to people who have faced similar situations. She said she started thinking seriously about a comeback bid about a month ago and decided over the weekend to run.
