(CNN) - The two senators responsible for how their parties will fare in November's elections agreed Sunday that Democrats will lose some seats, but disagreed on how many.
Republican Sen. John Cornyn of Texas, chairman of the National Republican Senatorial Committee, predicted a "tsunami" for the GOP, while Democratic Sen. Robert Menendez of New Jersey, head of the Democratic Senatorial Campaign Committee, said Democrats would maintain their Senate majority.
"It's going to be a wave election," Cornyn said on CNN's "State of the Union". "I don't know how high or how wide the tsunami will be, but I think it will be significant."
Menendez was more tempered in his response.
"The midterm election history of the president's party going back to the civil war means the president's party loses seats but the difference between a tsunami and losing some seats is the suggestion that they can take over the majority," Menendez told CNN Chief Political Correspondent Candy Crowley. "That will not happen."
And they couldn't agree on the Tea Party movement either.
Menendez said some words used by Republican candidates in this election cycle are "scary." He referred to candidates for Senate supported by members of the Tea Party movement including those in Nevada, Colorado, Wisconsin and Delaware. He specifically cited comments about witchcraft made more than 10 years ago by the Republican Senate nominee in Delaware, Christine O'Donnell.
"Those aren't my words, those are their words," Menendez said. "The problem for Republicans is that these candidates are out of the mainstream of where their general election is at."
Cornyn said the Tea Party movement has been "constructive and helpful."
"It's helped orient us to our limited government principles," Cornyn said. "But now that the primaries are over we're all unified and focused on our Democratic friends on November 2nd."
