USA-TAX/It’s not exactly a tsunami of euphoria. But Republican victories in the midterm elections may have helped goose economic optimism, at least among …well… Republicans.

A new Gallup survey finds that Republicans grew more optimistic during the first week of November, as Tea Party candidates led a GOP charge that captured the House and narrowed the Democratic majority in the Senate.

Republicans grew 13 points rosier on the Gallup Economic Confidence Index, compared with October, and that change appeared strong enough to drive an increase in optimism across the board.

In fact, Gallup suspects the overall performance could foreshadow improvement in the Thomson Reuters/University of Michigan consumer sentiment survey, which includes a barometer of current conditions that hit its lowest level since November 2009 last month. We’ll soon USA-ECONOMY/know. The next survey report comes out Friday.

Meanwhile, Gallup says other factors that may have helped make people happier on the whole include the surge on Wall Street, the Federal Reserve’s new $600 billion grove and a better-than-expected jobs report.
