Republican victories in the New Jersey and Virginia gubernatorial races this week are the first significant signs of frustration with Democrats since President Obama was elected one year ago.

New Jersey voters elected Republican Christopher Christie as their next governor over incumbent Jon Corzine in a Democratic party stronghold. Christie becomes the first Republican in 12 years to win statewide office in that state.

The key to victory in these races was independent voters, who voted for Democrats last year and switched to Republicans this year.

What has shifted the political landscape in just one year? Voters in both states cited concerns over the economy and joblessness. It’s no longer possible for Obama to blame these situations on his predecessor. These are now his problems and the nation is eagerly awaiting solutions.

The other concern on the minds of voters is pending health care legislation in Congress. While a large percentage of Americans want reform in health care, they’re concerned about the price tag for the solution being crafted by the Democrats.

Even with strong majorities in both houses of Congress, Democrats have been unable to deliver a health care bill to the president’s desk. This week Senate Majority Leader Harry Reid said it’s unlikely that Congress will pass health care reform this year.

Many voters are also very concerned about the likelihood of ballooning deficits stemming from the president’s health care plan, his economic stimulus package and ongoing joblessness.

This week’s elections should be a wakeup call to elected officials from both parties. The American people are frustrated with their elected officials and expect action on health care and the economy. Incumbents from both parties could be vulnerable next year if strong but financially sensible plans aren’t enacted.
