New campaign finance reports show Barack Obama entered April with $51 million in the bank to mount his campaign for the White House.

His cash on hand fully equipped him to confront Democratic rival Hillary Rodham Clinton in Pennsylvania, which votes Tuesday.

Obama’s fundraising in March led all candidates, but was still lower than the mark he set in February, when he raised more than $55 million. He has raised $235 million in his campaign.

Aides say Clinton raised about $20 million in March, but she had not filed her report with the Federal Election Commission a couple of hours before the deadline.

Republican John McCain’s report showed he raised $15 million and had nearly $12 million in the bank.
