Former Gov. Robert L. Ehrlich Jr. says he has amassed more than 20,000 individual contributions in his bid to unseat Gov. Martin O'Malley.

Ehrlich, a Republican, has not released campaign fundraising totals but says he will do so within the next 24 hours. This morning, O'Malley, a Democrat, said he and Lt. Gov. Anthony Brown had raised more than $3.3 million in the past four months and have $6.7 million in the bank. O'Malley campaign manager Tom Russell said the O'Malley-Brown ticket has more than 13,000 donors, including many who have given multiple times.

The campaign finance reporting period ended at midnight, and official numbers will be out next week. The previous report, which came out in January, months before Ehrlich made his reelection bid official, showed he had about $140,000 to O'Malley's $5.7 million.

Although Ehrlich said he wasn't ready to release his new totals, he called the amount he'd raised "pretty good." In an email earlier this week to supporters, Ehrlich said he was seeking their help in reaching $3 million raised since March.

"We hit the number we thought we'd need to hit to win the race," Ehrlich said after a campaign event this morning in Dundalk.

Ehrlich said he was "not unhappy" with the numbers that O'Malley posted, saying he'd expected him to raise more. However, the 2006 Ehrlich campaign raised $2.4 million in the same four-month period that this year's O'Malley campaign raised $3.3 million. (Sitting governors are not allowed to raise money during the January-April legislative session.) The state has more than double the number of registered Democrats as Republicans.
