Boehner ally: GOP can win Senate

A high-ranking House GOP lawmaker predicts big congressional wins for his party in November.

If Republicans don't make an unforced error, such as repeating last fall’s government shutdown or failing to raise the debt ceiling, veteran Rep.

MORE (R-Okla.) told The Hill that his party has a “very good chance” of picking up the six seats needed to take over the Senate.

Cole cautioned that his colleagues need to “make sure that we don't do something foolish” that could jeopardize a good showing in the midterms.

He said the GOP can’t allow Washington to “default on the debt or shut down the government -- things of that nature are actually the greatest political danger to us.”

In the Senate, Republicans are defending 14 seats this cycle, while Democrats are defending 21 seats.

The GOP could pick up seats in South Dakota, West Virginia, Arkansas, Louisiana, Montana, Louisiana and North Carolina, Cole said.
