Philadelphia ( CNN ) -- It 's a large district in and around Philadelphia . It 's not a swing seat ; it 's a safe Democratic strongholdâ€ ” not a nailbiter . But in this midterm election , the 13th Congressional District race has attracted some national attention and some rock star fundraisers : Bill and Hillary Clinton . Why such attention and star power ? Because the candidate is Marjorie Margolies : related by marriage to the Clintons and tied to the former President by history . Margolies first gained national attention 20 years ago . She lost her seat as a freshman House member after voting for Bill Clinton 's 1993 signature economic plan . It was about to go down after multiple Democratic defections . He needed one vote ; she was it . `` I do n't regret my vote , '' she said at the time . `` Nor do I apologize for it . '' Clinton remained in her considerable debt . Neither she nor the President could have known then that they would be bound in another way : Her son , Marc , married Chelsea Clinton , who is now expecting their first child . And while the Clintons have raised money for her campaign , they 're not exactly campaign regulars . In memoir excerpts , Clinton honors her mom . The political question : how much Clinton is enough ? `` We always knew that if they came in too much we would be blamed for their coming in too much . If they do n't come in enough , then people would say they did n't come in enough . You 're kind of damned if you do , damned if you do n't , '' Margolies told CNN . `` They have done everything we 've asked them to do , and I am running on what I have accomplished in the last 20 years and not on my affiliation with the Clintons . '' But that 's hardly something she can , or really wants to , escape . A campaign ad using Bill Clinton 's appearance on her behalf went up on the air Wednesday with him saying `` If you send Marjorie to Congress she will make you proud ... and this district will be well-served if you elect her . '' Hillary Clinton is headlining a fundraiser in New York City for her Thursday evening . And her vote to pass Clinton 's economic plan back in the day is a subject she does not shy away from as he campaigns in her old district that was once largely Republican , but is now largely Democratic . Predictably , she 's come under some criticism about how her campaign has used the Clintons . One of her opponents , Daylin Leach , released an ad featuring some of Bill Clinton 's remarks touting Margolies . Then Leach 's daughter comes on the screen saying `` While some cling to the past , we just ca n't go backwards . '' How many pro-Clinton super PACs is too many ? The campaign hopes the Clintons can gave Margolies a last minute boost in fundraising and turnout . `` I want to get one thing out of the way . I would be here if her son was n't my son-in-law , '' President Clinton said at a campaign event for Margolies last month . `` I 'm not saying vote for her because 20 years ago she saved the economy . '' She also saved the Clinton presidency , according to a top former aide , Paul Begalaâ€ ” and knowingly lost her job . `` I 'm quite sure he knew that that was a political death knell for somebody who had just won by the narrowest of margins . And he was very impressed by that , '' Begala said of the President 's reaction . Margolies remembers the day of that vote in August of 1993 . `` The Republicans were high fiving , saying it 's going down , '' Margolies recounted in the interview . `` A lot of Democrats were talking about changing their vote . '' The President called her . `` He said what would it take ? '' she recalled . `` I said I will only be your last vote . I know how important it is . '' That point was not lost on the President . Clinton and senior White House staff huddled around a small television in an office just off the Oval Office . They watched Margolies walk the plank . Hillary Clinton steps further into politics with Margolies fundraiser . `` Republicans stood there and taunted her and said 'bye bye Marjorie , '' said Begala . They were right . Her deciding vote may have saved Clinton , but she would end up losing her seat the next year . In the book of isn't-this-a-small-world , Margolies is now part of the extended Clinton family . In fact , she and the Clintons are preparing to be co-grandparents . But as voluble as she is on politics , she 's just as silent when it comes to the Clintons . When asked about family matters , she becomes downright monosyllabic . When asked if she has anything to say about her and Hillary Clinton being co-grandmothers she responded `` no . '' Asked if she and the Clintons are friends she said `` It 's an area that I will not get into , '' adding : `` They are lovely . The Clintons could n't be any nicer . '' And when asked what it was like for her son to marry into such a political dynasty , Margolies told CNN `` It 's surprisingly normal . '' That depends on how you define normal . As for the race itself , Margolies has a fight on her hands . She 's locked in a tight four-way Democratic primary despite being the early frontrunner . The district is now solidly Democratic and runs from the affluent suburbs into the blue-collar area of North Philadelphia . She campaigns as an advocate for abortion rights and boosting the middle class . She has been attacked by opponents for misusing campaign funds which she denies . She also got hit for not campaigning aggressively in the early days . She has ramped up her schedule and participated in more debates . How strong is Hillary ? Karl Rove is attacking her .
Former Rep. Clintons lost her seat 20 years ago after backing Chelsea Clinton on budget . Bill is her daughter-in-law , so she has a unique link to the former 13th family . And Bill and Chelsea Clinton are working to help her out in her political comeback bid . But there 's a fine line in gauging how much of the Clintons is enough in a political campaign .
