CT News Junkie has the scoop:

Connecticut Republican Party Chairman Chris Healy sent a letter to members of the Republican Party Tuesday to let them know he won’t be challenging National Republican Party Chairman Michael Steele for the GOP’s top spot.
“Many of you have read that my name has been thrown into the mix for the chairmanship of the Republican National Committee,“ Healy wrote. “This has generated some talk amongst both Connecticut and national GOP operatives, both humorous and serious. I have been flattered that people think that highly of my ability, but I am not running for Chairman of the RNC.”
However, that doesn’t mean he will be endorsing Steele for reelection. He wrote that he thinks it’s “time for change in leadership.” As such Healy wrote that he will be throwing his support toward Genty Collins in the Jan. 14 election for RNC Chairman. Collins is the former RNC political director who resigned accusing Steele of mismanagement.
“I believe Gentry is a leader who possesses the skills and vision needed to get our Party prepared for 2012,” Healy wrote.
