(CNN) - Doug Hoffman - the conservative third party candidate running in upstate New York's closely watched special congressional election - raked in $116,000 in the last 24 hours, a campaign spokesman confirmed to CNN.
The cash haul came the same day former Alaska Gov. Sarah Palin made a surprise endorsement in the race, voicing her support of Hoffman over the Republican Party's nominee, Dede Scozzafava.
But Hoffman spokesman Rob Ryan said much of the cash came before Palin made her endorsement public Wednesday evening, and is more a sign of the campaign's growing momentum in the race's final days. Other conservatives have also recently aligned behind Hoffman, including former Rep. Dick Armey, former Sen. Rick Santorum, and Rep. Michele Bachmann.
In recent weeks, conservative activists have launched massive online efforts urging supporters to donate to Hoffman in the race's final days to send a message to Republican Party leadership.
"It's sort of like what you saw with Obama…when you hit a certain critical mass of media attention, and the bloggers writing about you and everything else, it starts driving the money," said Ryan.
The election to fill the House seat for New York's 23rd district arose after former Republican Rep. John M. McHugh resigned the post to become secretary of the army. The campaign has exposed division amongst the GOP over whether to support the more moderate Republican candidate or the upstart third-party challenger whose stances are more in line with those of the conservative base.
