There's at least a seven in ten chance that Republicans will net the six seats the party needs to reclaim the Senate majority heading into the 114th Congress, according to the three major election models that aim to forecast the results of Tuesday's vote.

The Washington Post's Election Lab model casts the Republican takeover as a near certainty, giving it a 96 percent probability of happening. Nate Silver's FiveThirtyEight model says Republicans have a 73 percent chance at the majority, while LEO, the New York Times model, pegs it at 68 percent.
