Linda E. McMahon’s campaign for the United States Senate has been good for Bert Volpacchio, who received $494 for a meet-and-greet with about 40 local officials last May at his restaurant, the Hot Tamale, in Seymour, Conn.

It has been great for regular suppliers like Best Buy, Staples and BJ’s Wholesale Club; for restaurants that have provided meals for volunteers like No Anchovies in Cromwell and the Sushi Palace in North Haven; for specialty businesses like Bayview Balloons of Milford, which got $830 just before the Republican primary; and for political operatives large and small.

Ms. McMahon may or may not get to influence job creation as a senator. But she has already made an impact on the Connecticut economy by dishing out close to $100 million for two Senate races over the past three years, far more than anyone has ever spent of their own money to win any federal seat. She has long since blown by the $72 million Ross Perot spent of his own money on presidential bids in 1992 and 1996.

The result is akin to a medium-size business with roughly 200 employees, a network of 13 offices and a broad constellation of consultants, marketing experts and advertising firms that include a who’s who of Republican handlers and has had a virtual monopoly in the race on the expensive New York City television market that reaches southern Connecticut. The biggest recipient thus far has been Scott Howell & Company, a Texas media consulting company, which received $24.7 million, mostly for advertising in her unsuccessful 2010 race against Richard Blumenthal, according to her campaign finance disclosure reports. She has spent at least $11 million on printing and postage.
