(CNN) - Amy Kremer, chairman of the Tea Party Express, is vowing an aggressive independent expenditure campaign in support of Delaware Republican Senate nominee Christine O'Donnell and says of national Republicans' chilly distance: "She can win without them."
Speaking to CNN after O'Donnell's stunning upset victory, Kremer also predicted a wave of support from activists across the country: "We're behind her 100 percent and through technology people across the country are engaging in elections. I guarantee when people across the country hear comments from the national Republicans it will help with her fundraising."
Some national Republicans have said they do not plan to put money into O'Donnell's race, arguing that she can't win in November.
Shortly after her victory speech O'Donnell told CNN, "I would love their support but they're the sa0me so-called experts who said I couldn't win the primary" and, laughing, made a dig: "They don't have a winning track record."
Kremer echoed that message, telling CNN: "These people better start waking up and recognizing that people from out of the state can affect their future," adding "I wish they could put animosity aside because she's the true conservative but nothing surprises me out of the establishment these days."
She points out that Joe Miller – the tea party candidate in Alaska – won his Senate primary despite being grossly outspent by the party-backed candidate. Her organization, the Tea Party Express, also backed Miller's candidacy.
Kremer's organization has been enormously successful in backing insurgent candidates across the country this year.
The Tea Party express ran ads, sent mailers, and organized rallies in support of O'Donnell - Kremer herself came to the state to help build support.
She insists O'Donnell's victory is part of a national trend: "I'm extremely happy but not as surprised as everyone else because we have our pulse on America. Pundits need to pay attention to what's going on – it's not the establishment, it's the fire belly that's winning these elections and that can't be bought."
