President Obama raised that amount, almost nine million dollars less than what he raised in March, with more than 400,000 people contributing.
Obama's April fundraising haul fell short of the $53 million he raised in March. That's as his campaign said more than 400,000 people contributed to the campaign last month, including 169,000 new donors.
"This election is going to be close, given the historic challenges this country faced when the president came into office," campaign manager Jim Messina told supporters in a YouTube video released Wednesday.
Obama's fundraising announcement came the same day the Republican group Crossroads GPS said it would spend $25 million on ads critical of the president. Crossroads is the non-profit arm of American Crossroads, a "super" political committee backed by former George W. Bush adviser Karl Rove that has raised about $100 million this election to defeat Obama.
