Obama raises $90 million in first half of October

President Obama's campaign raised a little more than $90 million in the first half of October, his campaign announced Thursday afternoon.

"In the first 17 days of October, 1,251,291 people came together to raise $90,500,000 for the campaign and combined committees," according to a Tweet from the Obama campaign.

Romney's campaign announced previously that it raised $111.8 million in the first 17 days of October.

Both campaigns' fundraising numbers include both the campaign and the party committees, as well as other groups.

The Obama campaign had its best fundraising month to date last month, when the campaign raised $181 million. Through September, the Obama campaign had raised $567 million, while Romney's campaign had raised $361 million through September.

With the October fundraising, the two campaigns have combined to raise more than $1 billion. Both parties are also benefiting from hundreds of millions of dollars in spending by outside groups.
