AUDIE CORNISH, HOST:
And I'm Audie Cornish. Two candidates for U.S. senate are finishing up a frantic day of campaigning in Massachusetts. Tomorrow is the special election to fill the seat vacated by Secretary of State John Kerry. Veteran Democratic Congressman Ed Markey is running against Republican businessman Gabriel Gomez.
They're each working hard, even if the public is a little ho-hum about it, as NPR's Tovia Smith reports.
TOVIA SMITH, BYLINE: It's hard not to compare. For the second time in just a few years, it's another special Senate election where a charismatic Republican with an intriguing resume is trying to grab a seat held by a Democrat for decades. Scott Brown shocked everyone when he pulled it off. Gabriel Gomez is trying to do it again.
GABRIEL GOMEZ: The people that are going to vote for me are enthusiastic. We've given them a reason to vote for someone.
SMITH: Gomez, a former Navy SEAL, Latino investment banker, is trying to rally support even as polls show him trailing Ed Markey. While Scott Brown won by claiming the stakes couldn't be higher, Gomez is closing his case by arguing the opposite, that it's just a 17-month term, so really no harm giving a new guy a try.
GOMEZ: You give me 17 months, I'll keep my word. If you don't like what I've done after 17 months, then you can vote somebody else in.
SMITH: For his part, Markey says he's taking nothing for granted, imploring Democrats to vote - a point that was repeated by Vice President Joe Biden over the weekend.
VICE PRESIDENT JOE BIDEN: Don't put yourself in a position where you get up Tuesday morning and you say, but, god, if I'd only gone down one more block, if I'd only made 20 more calls.
SMITH: Biden is only the latest in a parade of big-name Democrats who have stumped for Markey, including President Obama, Mrs. Obama and former President Clinton. Gomez has drawn in fewer big names, Senator John McCain and former New York Mayor Rudy Giuliani.
CHRIS KEOHAN: Having Republicans nationally come in is definitely a double-edged sword.
SMITH: It is tricky, says Democratic consultant Chris Keohan, to run as an independent-minded Republican in the very blue state of Massachusetts. But, he says, the national party still could have done more than they did for Gomez.
KEOHAN: He's got a great bio. He helps with all the demographics that Republicans historically have done poorly in. You would think that Gabriel Gomez would be exactly what Republicans would try to make their poster boy nationally. And to be honest, it really looks more like they've abandoned him.
SMITH: Even Scott Brown, still popular in Massachusetts, has been quiet, making his first rally with Gomez tonight.
MAURICE CUNNINGHAM: A little bit too little, too late, I think.
SMITH: UMass, Boston political science professor Maurice Cunningham says, at this point, probably nothing could bump Gomez into another political shocker.
CUNNINGHAM: I always like to use a quote from Donald Rumsfeld about the unknown unknowns, and, sure, of course, but we've had two, the Boston Marathon and the scandals in the Obama administration, but neither one has really affected the race.
SMITH: While Scott Brown built his win on the compelling case that he would be the critical 41st vote against Obamacare, Gomez's core issue of change is more amorphous. Since primary night, he's been mocking Markey for his 37 years in office.
GOMEZ: Eight-track players were big, the first "Rocky" movie had just debuted and that was when Ed Markey first got elected to Congress.
SMITH: But Markey has been pitching his tenure as an asset to voters who have just lost two veteran senators and has been hitting hard on core Democratic issues like abortion and gun control.
REPRESENTATIVE ED MARKEY: So ladies and gentlemen, we have to make sure that our cities are safe. Gabriel Gomez says he opposes an assault-weapon ban.
SMITH: Ultimately, Republican consultant John Sivolella says, Markey has managed to run successfully as a virtual incumbent.
JOHN SIVOLELLA: I think Ed Markey's kind of strategy paid off, just keeping it flat. I think just laying back and playing defense has worked for him. There was no reason for him to go out on a limb and do anything, you know, risky.
SMITH: Indeed, one day before the election, many voters are still more focused on the Boston Bruins and Fourth of July picnics than politics. Low turnout will likely help Markey, giving what Keohan calls the Democrats' well-tuned get-out-the-vote machine.
KEOHAN: They knocked well over 50,000 doors just on Saturday alone. There's really no on-the-ground solid operation on the Republican side. It's like they rebuild the wheel every two to four years.
SMITH: Whatever happens tomorrow, Gomez himself seems to have taken to heart his own message that this term is only 17 months long. He's already hinting at another run. Tovia Smith, NPR News, Boston.
