The word "impeachment" is still in the Constitution--nobody took it away. We can have another federal level election in 2014, which is when some senators and some house representatives are either replaced or re-elected. Those are the mid-term elections because it happens between presidential elections. And we can have another presidential election in 2016.
In the meantime, we have a properly re-elected president who has provided zero excuses to impeach him for. People who think otherwise because he's continued Dubya's drone program need to read Article 3 Section 3 first before hollering about Due Process. He's covered.
