Republicans Haley Barbour and Sarah Palin cast the Nov. 2 election as a repudiation of President Barack Obama’s policies and a “political earthquake” that will blow Democrats out of office.

Democrats, in making their closing arguments to voters on the Sunday talk shows, said their party may still keep control of the House of Representatives. If they don’t, voters will expect Republicans to compromise with Obama in order to trim the budget deficit, Democratic National Committee chairman Tim Kaine warned on NBC’s “Meet the Press” program.

“It’s going to be a political earthquake and the message will have been sent to the left that they blew it,” Palin, former governor of Alaska and Republican vice presidential nominee, said on “Fox News Sunday.”

“It’s not a lost cause,” Representative Chris Van Hollen, head of the Democratic Congressional Campaign Committee, said on Fox. “All these Washington pundits are going to be surprised.”
