This article makes a lot of assumptions for the 2016 elections, can you find them all?

In 2016, however, the Democrats foresee more favorable conditions. Not only is voter turnout expected to be much higher, but the economy will likely have had two more years to improve following the Great Recession.
On top of that, the demise of centrist Democrats in purple districts in 2014 means the party won’t be forced to play defense in the most contested races in the next cycle. And the Democrats are also hoping a strong presidential candidate - someone like presumptive contender Hillary Clinton - will excite the party’s base and provide candidates with lengthy coattails.
“In a presidential election with a Democratic nominee winning 53, 54 percent of the vote nationally - which I think is quite plausible with Hillary - she’s going to outperform that in the purple districts and create some real updraft,” said one former Democratic lawmaker.
