Bernie Sanders' presidential campaign raked in $2.6 million in just a few hours following his New Hampshire primary win Tuesday night, according to Politico. In his victory speech, Sanders made a fundraising pitch so he could continue "to take the fight" across the country.

"I am going to New York City tonight and tomorrow, but I'm not going to New York City to hold a fundraiser on Wall Street. Instead, I'm going to hold a fundraiser right here, right now, across America," Sanders said, according to The Hill, directing supporters to his website, which crashed from all of the traffic it received. He added: "Help up us raise the money we need to take the fight to Nevada, South Carolina and the states on Super Tuesday."

Sanders has increasingly made the Clinton camp nervous with his fundraising. In January, Sanders outraised Clinton $20 million to $15 million, mostly from small donors.

Sanders drew in more than $33 million during the fourth quarter of 2015, just short of the $37 million that Clinton raised in the same three-month period, according to The Washington Post. Most of Sanders' fundraising came through online donations from 2.5 million people during 2015, which surpassed President Barack Obama's record number of 2.2 million donations in 2011, the Associated Press reported. The average donation was $27, which will allow the campaign to ask contributors to donate again. Only a few hundred gave the $2,700 maximum.

In contrast, Clinton, in acknowledging her loss to supporters Tuesday night, said, "More than 700,000 people have contributed to this campaign, the vast majority giving less than $100," The Washington Post reported. She added: "I know that doesn't fit with the narrative. I know there are those who want to deny the passion and the purpose you all show every day for this campaign, but you are the reason that we are here and you are the reason we are going to win the nomination, and then win this election together!"
