If you think 2017 was an interesting year, just wait. 2018 promises to be even more of a roller coaster.
The new year brings deepening crises, confrontations and events that could shake Washington to its core and trigger shock waves that will test American unity, global peace and the cohesion of the Trump presidency itself.
Special counsel Robert Mueller's Russia investigation could come to fruition in 2018, and any finding of wrongdoing by Trump or close associates could cause a constitutional imbroglio.
Abroad, the North Korean crisis -- a brewing showdown for 65 years across the world's last Cold War frontier -- is reviving fears of nuclear war for the first time since the demise of the Soviet Union.
And one particular date looms on the calendar: November 6, when congressional elections take place that could see a Democratic wave neuter the Trump presidency. But if Trump -- currently with an approval rating below 40% -- can beat the midterm curse, possibly lifted by a rising economy, he could position himself for re-election in 2020.
Then there are the national and international crises -- mass shootings, economic meltdowns, terror attacks, natural disasters and geopolitical confrontations -- that test every White House and shape each year's politics. CNN
Trump and Congress have a challenging year ahead. How they handle the issues, and the elections, could be surprising. Buckle up, it is going to be a wild year.
