Happy Election Day, America. Things have changed since the last time everyone went to the polls. Then, Barack Obama was re-elected to a second four-year term. Now, he's been largely benched by his party, spending less time on the campaign trail than his much more popular wife, first lady Michelle Obama, former president Bill Clinton and potential future presidential candidate Hillary Clinton. Midterm elections are more local affairs and the issues vary from contest to contest.

But midterms have national consequences, and what happens Tuesday will help determine what President Obama can get done in his final two years in office. It will tee up the coming 2016 presidential contest and give Americans the chance to try on a more powerful GOP as they start to think about who should be the next president.
