WASHINGTON ? One of the key players in a special Democratic congressional primary Tuesday in Chicago comes from New York.
That city's mayor, Michael R. Bloomberg, is using his vast wealth to challenge a candidate running on a gun rights platform in the first election since the school shooting in Newtown, Conn. ? a move that underscores his crusade to serve as a political counterweight to the National Rifle Assn.
The NRA has chosen not to counter Bloomberg's ads attacking its preferred candidate, former Rep. Debbie Halvorson, and liberal Chicago districts are an imperfect test case. But Bloomberg's lavish participation in the race may be enough to cause political ripples, as other lawmakers are put on notice that next time, the mayor's millions could be spent in their districts.
"Folks running for office are going to have to stand behind their record," said Stefan Friedman, spokesman for Bloomberg's "super PAC," Independence USA.
Gun rights supporters have clearly gotten the message. Richard Pearson, executive director of the Illinois State Rifle Assn., said his group was caught off-guard by the mayor's surprise attack, and he warned sympathizers in other states: "Bloomberg is coming to your state. Be ready."
The race is for the seat that was held by Jesse Jackson Jr. until his resignation last fall. His congressional tenure was cut short by mental health troubles and allegations of ethical lapses. More than a dozen Democrats have launched bids to replace him; in the solidly liberal district, the primary winner is almost certain to win in April's general election.
Halvorson has tried to distinguish herself from the large Democratic field, and to appeal to voters in a rural portion of the district, by supporting the right to carry concealed weapons and opposing an assault weapons ban. Bloomberg's advertising barrage has relentlessly attacked Halvorson, who has an "A" rating from the NRA, and has championed Cook County administrator Robin Kelly, who has made support for new gun laws a centerpiece of her campaign.
The district includes predominantly African American communities in urban southern Chicago and its nearby suburbs, and neighboring rural areas that are largely white.
Even before December's shooting in Newtown, gun violence was destined to be a central election issue. Chicago recorded more than 500 homicides in 2012, and the vast majority of those deaths were linked to firearms.
By spending $2.2 million on anti-gun ads, Bloomberg has propelled the race into the national spotlight, prompting other advocacy groups to jump into the fray.
"This is our first chance to beat the NRA this year," exhorted Democracy for America, a Vermont-based organization that is an offshoot of former Gov. Howard Dean's 2004 presidential campaign, in an email to supporters.
"We absolutely should see this as a bellwether," said Arshad Hasan, the group's executive director. "It is a referendum on the power that the NRA has."
Political analyst Stuart Rothenberg cautioned against viewing this special election as an indicator of larger trends.
"This is not a district somehow reflective of the nation as a whole," Rothenberg said. "The gun issue is going to play differently there than it will in rural Ohio or the South or a number of places."
The Halvorson campaign says the economy, not guns, is the top concern of voters in the district.
"We're just not going to let a guy from N.Y. dictate what's going to happen in this election," said Sean Howard, spokesman for the Halvorson campaign.
The NRA has kept a low profile in this race, opting not to weigh in with its own television ads or direct mail. The only advocacy for gun rights has come from the Illinois State Rifle Assn., which sent mailers on Halvorson's behalf to its several thousand members in the district.
This is not Bloomberg's first foray outside of his home state.
In 2012, Bloomberg spent $8.2 million on five House races, targeting candidates with top marks from the NRA. Three of his preferred candidates won; in one notable coup, his super PAC helped defeat Rep. Joe Baca (D-Calif.) by spending more than Baca and his opponent combined. The television ads in that race did not focus on guns, as the Illinois ones have.
Democratic strategist Bill Carrick said Bloomberg's spending in Chicago demonstrates that his political activism will be sustained.
"I don't think he's going away," Carrick said. "I don't think, win or lose, they'll overreact to results of one election. They're just going to keep on coming."
