Former Nassau County Executive Thomas Suozzi said he has raised $450,000 so far in his bid to run for retiring Rep. Steve Israel’s Third District seat, Suozzi’s campaign spokesman said.

Suozzi spokesman Mike Florio said the figures show that Suozzi has, “tremendous amounts of support for this race.”

Florio, who said the campaign still is compiling the formal campaign finance report due April 15, said Suozzi has about $320,000 cash on hand for the June 28 primary. None of Suozzi’s money comes from donations or loans from himself or family members, Florio said.

Suffolk County Legis. Steve Stern (D-Dix Hills), who has hired most of Israel’s former campaign aides, declined to say how much he has raised so far. Jon Kaiman, former North Hempstead supervisor, did not return calls for comment

Reginald Johnson, campaign treasurer for Democrat Anna Kaplan, a North Hempstead town board member, declined to say how much Kaplan has raised, but said it would be “similar” to Suozzi’s amount.

Democratic contender Jonathan Clarke, an attorney from Jericho, said he has raised $800 so far. He said candidates who raise “enormous sums are only showing how out of touch” they are with voters. He has called on all candidates to limit their spending to $300,000 and forgo any third-party spending.

Kaiman has estimated the June 28 primary alone will cost candidates $1 million each, while Stern put the figure at $2 million.
