It's not just because people are becoming more pro-Republican that the GOP is seeing a surge in the pre-midterm congressional election polling.
According to the latest Gallup poll, much of that support for Republican candidates is the result of frustration with the Democrats. A sign that Republicans shouldn't view their anticipated takeover of the House of Representatives as a sign that Americans have suddenly gotten Republican religion.
Perhaps, instead, it is more the result of unfulfilled expectations.
President Obama rode to the White House on a crest of the promise of Hope and Change. Perhaps he promised too much or bit off more than he could chew. Because now there's a backlash over expectations that no president could ever have fulfilled.
As the Democrats so successfully said during Bill Clinton's campaign against President George H.W. Bush, "it's the economy stupid." The promise of recovery - by funding "shovel ready" projects - hasn't materialized.
People are still out of work or fearful they'll join the ranks of the unemployed. Consumer spending remains down - and consumer spending is the biggest stimulus the economy could enjoy.
All this uncertainty translates into a distrust of incumbents - especially those seeking reelection who have a (D) after their names.
Republicans will be celebrating in November - as well they should. But there should be a temperance to that celebration. Because, come January, they will share in the power. And that means they'll share in the responsibility - and the blame if things don't get better - of government.
In the end, winning, and being in power, especially in tough economic times, can be a double edged sword. If you don't believe it, just ask any Democratic office holder.
