I think the next US President will be Clinton and it will be a cakewalk for her. The GOP doesn't really want 2016 in my opinion. In the coming years, the GOP would rather be regarded as the opposition party. Clinton will be our oldest president since Ronald Reagan, which means she will be 69 at the beginning of her first term and 73 at the end. The stress of the job and campaigning will mean that when she leaves office after a second term at the age of 77, she will be weakened and tired.
During her second term, I could see the government spending bubble bursting, similar to Greece. Her first term will see us doing everything possible to prevent this. This means major military spending cutbacks and reduction in overseas bases. We may have to give up Europe and East Asia to full independence. Basically, she will have the unenviable task of switching us to a peacetime economy from the wartime economy we have been on since 1941. The trick will be doing this seamlessly without causing a recession while gaining support from the Republicans. She might have to trade things that we don't want her to trade. For the past 5 years, the police have been getting heavier equipment, armor and weapons (drones, tanks, etc.) from the federal government. In 5 more years, we'll be used to it and won't remember it being any other way. So if a crash does come, the people won't be able to make much of a fuss.
