It won't be accomplishments, it will be fear mongering and mud slinging that will get him another term.
The entire campaign will be based around him being the better choice simply because they will make the GOP candidate seem like he personally killed Mother Teresa.
Then they will kick in with "it could be worse" by making sure the country believes a Republican in the White House will
--end all unemployment benefits
--raise health care costs
--cut all government programs
--cut taxes on the rich
--do away with public schools
They won't focus for a second on what he hasn't done, except in rebuttal to a GOP ad in which case they will blame the Republicans. The focus will be on what will happen if he isn't there watching out for the little guy.
