So much for a Rob Simmons comeback. 

New numbers from Quinnipiac show former World Wrestling Entertainment CEO Linda McMahon pulling away from former Rep. Rob Simmons (R) in Connecticut's Republican primary for Senate.

McMahon leads Simmons 50 percent to 28 percent, with businessman Peter Schiff polling at 15 percent.  

A Q-poll from last week had showed Simmons making up some ground after restarting his Senate campaign a few weeks ago. Simmons has run two TV ads and made a handful of campaign appearances during the past three weeks. 

He had suspended his campaign back in May after losing out on the party's endorsement at the Republican state convention, but never bowed out completely. 

In a statement Monday, McMahon spokesman Ed Patru said the campaign is confident that primary voters will back McMahon Tuesday, calling her "the only fiscally conservative outsider with a record of job creation who can beat Dick Blumenthal."

Meanwhile, the Democratic primary for governor in Connecticut is in a dead heat ahead of primary day. 

Businessman and one-time Joe Lieberman opponent Ned Lamont holds a 3-point lead over Stamford Mayor Dan Malloy — 45 percent to 42 percent.
