GOP : 463
Dems: 65
Way this is possible
If the oil and energy market crash early 2016
ISIS holds American members and Obama doesnt do anything about it
Obama raises taxes on everyone through executive order
Democrats nominate Joe Biden who gets crushed like this due to these events horrid convention and getting crushed in debates
Another way is if Bernie Sanders is nominated and goes even further to the left then he even is with a few of the above events happening
Dems 456
GOP 52
Ways this happens
Obama approval goes through the roof
Economy is as booming as late 90s
On path to surplus in two years
ISIS gets destroyed
Dems nominate Hillary and crush Cruz
