Republican Mark Greenberg plans to dig deep into his own pocket to fund his campaign for Congress

Greenberg pledged to spend $1 million of his own money in his quest to win the 5th District seat.

Greenberg also said he plans to start the process of gathering signatures to force a primary. Two of his GOP rivals, Justin Bernier of Plainville and Sam Caligiuri of Waterbury, have been busy lining up delegates in advance of the party’s May 21 convention. (Just this morning, Caligiuri was trumpeting the endorsement he received from former Newtown state Rep. Julia Wasserman.)

Thus far, the GOP establishment, both locally and nationally, appears to be favoring Bernier and Caligiuri. Both men are on the NRCC’s radar (though Caligiuri is still not listed on the program’s website.) But given the National Republican party’s current fundraising issues, a wealthy candidate who is able to write his own checks might have some appeal. 

Greenberg, a businessman from Litchfield, says he’s “in this race to win.”

“Of all the Republican candidates, I alone have the ability to stand toe-to-toe with Chris Murphy and his PAC and special interest money,” he said in a statement released this morning. “I also bring the perspective of a businessman who did not create our country’s problems, but who knows how to fix them.”

Greenberg announced last week that he has $403,282 in his campaign account. He said he  raising $77,335 during the first quarter of 2010 and lent the campaign an additional $271,500.
