"Unfortunately, this is what Sen. McCain's inside Washington ways look like," said Romney-for-president campaign manager Beth Myers. "He cut a backroom deal with the tax-and-spend candidate he thought could best stop Gov. Romney's campaign of conservative change."
The Huckabee campaign denied there was any deal.
"I'm sorry, I thought the Romney campaign sent out something [on Monday], saying there's no whining in politics," said Saltsman. "He got beat — period. Once again, showing that Gov. Romney's millions of dollars can't buy the election."
Bob Fish, the CEO of the West Virginia Republican Presidential Convention, responded to Romney's accusations of a deal by telling ABC News, "Welcome to politics."
"To anyone who speaks of 'a deal' being made, as if that's critical, I guess I would say, 'Welcome to politics.' This is exactly what happens when you have an election of this type," Fish said.
