Republicans have, for the first time, been projected on Friday to win control of the US Senate by an elections analysis website.
"Our model currently predicts that Republicans have a 50.4% chance of control, and our mean seat projection is 51 (R) and 49 (D)," the DecisionDeskHQ website wrote on Twitter.
The modeling includes a 3.9% increase in Republicans gaining Senate control over the past day, and a 14.2% jump through the past month.
There continues to be three main battleground states that will prove pivotal for the Senate, including races in Georgia, Nevada and Pennsylvania. Democrats have a greater chance of winning in the two former states, but DecisionDeskHQ says Republican celebrity doctor Mehmet Oz has a 7% greater chance than Lt. Gov. John Fetterman of winning in Pennsylvania.
This year, 35 Senate seats are in play, with the vast majority -- 21 -- being held by Republicans. All 435 seats in the House of Representatives are being contested as well.
