Mitt Romney the presidential candidate from the Republican Party is now taking in donations from those who were backing his onetime fellow Republican rivals during the primary season.

Romney raised over $23.4 million last month and that included over $634,000 from 225 contributors who had previously donated the maximum $2,500 to the campaigns of New Gingrich, Rick Perry or Rick Santorum.

Sheldon Adelson, a casino executive, and his family, who contributed over $21 million to a super PAC that supported Gingrich, donated $10 million during June to a super PAC that is pro-Romney known as Restore Our Future. Robert Brockman, a successful Texas businessman, who gave $50,000 earlier to a super PAC that supported Perry through his businesses, has now given $1 million to super PACs that support Romney.

A number of donors gave Romney $5,000, who became the first Republican since 1972 to raise private dollars for the election. Congress since the Watergate scandal and Nixon’s resignation has offered public finances for those candidates who forgo raising private money. This year, both Obama and Romney opted for receiving all private money, as Obama did as well in 2008.

Romney started June with over $17 million left to spend, but little compared to the $109 million that Obama has saved. The gap has been narrowed however, as the National Committee for the Republican Party reported that over $60 million was on hand to help Romney. That amount was more than double the $29.7 million the Democratic National Committee reported it had for Obama.
