(THE HILL) — Banks are breathing a sigh of relief after established GOP incumbents bested a handful of Tea Party challengers at the polls recently.

Industry sources said the establishment wins improve Republican odds of retaking the Senate, which would in turn lead to a friendlier climate for the long-beleaguered sector. But some note that the Tea Party has left a mark on the Republican Party, presenting a challenging landscape for the industry.

The Tea Party movement can trace its roots back to fury about bailouts and banks, but the force that pulled the Republican Party right in recent years is finding less success at the polls recently.
