Although President Barack Obama raised more money overall throughout his campaign, Mitt Romney has received some big donations making him the leader in fundraising for October, according to Reuters. 

Romney received $10 million from casino millionaire Sheldon Adelson toward his campaign. He also received a significant amount from super PAC American Crossroads, directed by Karl Rove. 

Super PAC Restore Our Future donated $12 million for an ad campaign in favor of Romney that will target the key battleground states for six days leading up to Election Day. 

Before this donation, Obama’s campaign had been outspending Romney on advertising in the battleground states, according to The New York Times. 

These ads could help Romney gain voters in these states and utilize his recent spike in the polls. 

Obama is also recieving some important last minute donations. Super PAC Priorities USA Action has been one of Obama’s main contributors. 

First Lady Michelle Obama is helping her husband’s fundraising efforts in the final week before the election.

She sent out an email to residents in North Carolina and Virginia saying, “Barack needs you. Please chip in $5 or whatever you can today," according to NewsBusters.

Outside groups have spent more than half a billion dollars on advertisements just in October, according to Politico. 

Reuters reported that this presidential race has been the costliest in U.S. history. This could largely be in part to the Supreme Court’s 2010 Citizens United ruling, which allows groups and individuals to spend unlimited amounts of money in support or against a candidate.
