The on-again, off-again Senate campaign of former Rep. Rob Simmons (R-Conn.) is apparently back on again less than two weeks before the Aug. 10 primary.

At a debate Tuesday night with businessman Peter Schiff, Simmons said, "I am running for the United States Senate," something he has not said with clarity over the past two weeks despite a recently launched statewide TV ad buy.

Simmons suspended his primary campaign after he lost out on the party's endorsement to former World Wrestling Entertainment CEO Linda McMahon in May. McMahon has largely been focusing her fire on state Attorney General Richard Blumenthal (D) since then.

McMahon did not take part in Tuesday's primary debate, leaving the stage to Schiff and Simmons, whose intentions on the race were still unclear prior to the event.

In an interview with The Hill last week, Simmons denied his ad buy signaled a resumption of his primary campaign. Simmons labeled the ads "public service announcements," and said he simply wanted to ensure his supporters knew his name remained on the Aug. 10 ballot.

Simmons had pledged not to seek the nomination if he didn't win the party's endorsement at the state convention.

The McMahon campaign has criticized Simmons's indecision, but has thus far not re-focused any campaign attention on the former congressman.

But if Simmons plans to actively campaign across the state in the final stretch of the primary, McMahon will likely have to pay some attention to him, even though he lacks a staff or any real campaign infrastructure.

The Associated Press reported early Wednesday that Simmons's wife and daughter will handle his schedule for the remainder of the campaign.
