Former senator Lowell P. Weicker Jr. (R-Conn.), running for governor of Connecticut as an independent, appeared last week to have passed the legal hurdle in his comeback bid by filing more than 105,000 petition signatures -- 10 times the number he needed to get his name on the November ballot.

"Politics will never be the same," Weicker told about 250 supporters gathered on the lawn of the state Capitol in Hartford, where he submitted the signatures to the secretary of state's office.

"Simply put, the people of the state of Connecticut are saying to the Republicans and the Democrats . . . 'Enough,' " he said. "This time it's our turn."

Under state law, Weicker, who is running as a member of "A Connecticut Party," needed 9,937 nominating signatures --

1 percent of the voters who cast ballots in the 1986 gubernatorial election.

Every poll since March, when he entered the race, has showed Weicker holding a large lead in three-way matchups against Rep. John G. Rowland (R) and Rep. Bruce A. Morrison (D).

Gov. William A. O'Neill (D), a two-term incumbent whose popularity suffered as the state's economy weakened and taxes increased, decided not to run

for reelection three weeks af- ter Weicker entered the campaign.
