, who ran in last year's race as an independent write-in candidate, became the first GOP candidate to enter the race, though he hardly appears to be a major threat: he was only able to garner 559 votes in 2010.
, the wealthy self-funder who lost to now-Sen. Richard Blumenthal
, D-Conn., last year is also considering a bid. And it's also possible that former Rep. Rob Simmons
, R-Conn., who ran in the GOP primary last cycle, but lost to McMahon, could run.
"McMahon has been going around, meeting with people, attending a lot of political events," said Healy. "She's been pretty public in her appearances, so she's making all the moves that would indicate she is going to run, but we will see what happens in the next several weeks or months."
McMahon recently said
she is giving strong consideration to another run.
Regardless of who emerges from the Republican primary, the race is still very much an uphill climb for the GOP, who faces even more of a headwind in a presidential year.
According to registration and party enrollment statistics from October of 2010, there are 1.8 times as many total Democratic voters as Republican voters, in a blue state where both President Obama
and Sen. John Kerry
, D-Mass., won comfortably in 2008 and 2004, respectively.
