2016 will also be very different if the Democrats do not have a minority candidate, and one as popular as Obama. You throw Clinton in there and the Republican smear machine will be raking the Clintons over the coals like it's 1999--good old fashioned mud slinging (and no one calling the other a racist).
Let them try. Even with his sex scandal, Bill Clinton left office with a 68% approval rating. One of the highest in U.S. history. Hillary Clinton's current job approval rating is 70%. If the Republicans want to be relevant in 2016, they better find a viable candidate, and focus on what he/she brings to the table. If the try to run another campaign with a candidate that has no real plan other than a few talking points and is far to the right on social issues, they'll get crushed again.
