Obama collected donations from 162,286 Pennsylvania voters, compared to Clinton's 95,415, netting the Illinois senator $31.7 million compared to Clinton's $22 million in February, The Philadelphia Inquirer said Sunday.

Clinton's campaign finances closed the gap on Obama, however, with Pennsylvania contributions increasing by 264 percent from January to February, while the Obama camp increased its contributions by only 73 percent.

But 4,400 Pennsylvania voters threw Obama some $882,144 in February, compared to only 3,000 donors giving $665,106 to the Clinton campaign, the Inquirer said.

Since the start of the presidential campaign, Clinton has raised $124 million for her bid for the White House while Obama raised $133 million, the newspaper said.

The Pennsylvania primary will be conducted April 22.
