Rubio wins the Republican Nomination
Clinton wins the Democratic Nomination
Clinton wins the White House in a close popular election but dominates the Electoral College thanks to current Democratic structural advantages.
The Democrats gain 3 seats in the Senate leaving the Republicans a slim 51-49 majority. Democrats make small gains in the house (10-12 seats), but no massive coattail effect, and Republicans keep a majority, losing their most moderate members from purplish districts.
