According to the latest polling data, Democrats are expected to win a majority of seats in the House of Representatives.

FiveThirtyEight, a website focused on polling predictions, has estimated that the democrats have an 82 percent chance of winning control of of the House. There’s an 80 per cent chance that democrats will gain 18 to 53 seats, with an average estimated gain of 35 seats.

The “Blue Wave” is a movement in which voters are expected to swing left. Several models indicate that the wave is real, and that we will start seeing many more Democratic members in both the house and senate. However, FiveThirtyEight predicts that republicans will keep control of the senate.

FiveThirtyEight uses computer simulations to run the chances of different political outcomes based on polls and other indicators, according to its website.
