A top Democratic Party official says former U.S. Senator Gary Hart probably won't run for the Senate this year.
New Jersey Democratic Senator Jon Corzine is the party's top recruiter for Senate races. On Tuesday, he said the issue for Hart is money. A Senate race can cost millions of dollars.
Speculation about Hart has swirled since Democratic Congressman Mark Udall said last month he won't challenge Republican U.S. Senator Ben Nighthorse Campbell.
Hart declined to comment.
