Voter's Guide -- In Their Own Words | Mobile users tap here for videoThe Maryland State Board of Elections is investigating complaints that voting machines are flipping Republican votes to Democrat. Complaints of vote-flipping, as some call it, are coming from as many as nine Maryland counties, including Anne Arundel, Montgomery, Frederick, Howard, Queen Anne's and Baltimore counties. State elections officials said they have a team of people looking into the complaints.Some of the concerns are turning out to be anecdotal. For example, someone using the Towson University early voting center tweeted that the machine flipped their vote but no complaint was made to the judges.Chief Democratic Judge Denise Isaac said voters always get the last say on whether their ballot was cast the way they intended."When they've completed, the machine reviews everything they've voted so they can see, they can check and make any changes that they want," Isaac said. "The final vote is not cast until that person has a chance to look at everything that they've voted and they make their final decision."A female voter in Howard County did complain to a judge. She told 11 News by phone that when she cast a ballot at the library for a Republican candidate on machine No. 18, the machine beeped and then her choice flipped over to the Democratic candidate. She said this happened repeatedly. Finally an election judge gave her a pencil with an eraser head to punch in her choice and that worked.Officials in Frederick County believe the so-called vote-flipping problem was a "calibration issue" and they said a machine was removed from service and replaced.A similar complaint made in Anne Arundel County resulted in the machine being taken out of service and replaced.State election officials said they received reports that 20 voting units displayed a candidate different from what the voter selected. Twelve of those machines were thoroughly tested and the issue could not be replicated. The remaining eight units were taken out of service."We have a good system of checks and balances because we certainly want to let our voters know what we are doing is accurate," Isaac said.State election officials said similar complaints are filed during every election and post-election reviews indicate it's usually caused by voter error.Early voting continues through Thursday. So far, almost 118,000 registered voters have cast early ballots, which is about 3 percent of eligible voters.Meanwhile, both candidates for governor are busy trying to win over voters.Democratic candidate Lt. Gov. Anthony Brown has three campaign stops planned in Prince George's County this week. He'll be getting help from Hillary Rodham Clinton, who is scheduled to attend a rally for Brown on Thursday at the Ritchie Coliseum on the University of Maryland's College Park campus.Clinton was supposed to attend a Brown fundraiser last month but backed out to spend time with her new granddaughter. Her husband, former President Bill Clinton, came in her place.Meanwhile, Republican Larry Hogan has planned news conferences in Hagerstown and Frederick to talk about jobs and the state's heroin epidemic.Hogan is getting another show of support from New Jersey Gov. Chris Christie, who will be campaigning with him this week. It's Christie's third fundraiser in Maryland in the past two months. On Sunday, Christie appeared on Fox News, where he said the country should keep an eye on Hogan and the race in Maryland because he is "doing a good job in a very blue state."WBAL-TV 11 News reporter David Collins contributed to this report
