Democratic candidates are projected to win the U.S. Senate races in the battleground states of Kansas and Iowa.

As of 11:23 p.m. on the 3rd (EST), with 89.4% of the vote counted in Kansas, Democratic candidate Adam Hamilton received 52.1% of the vote, putting him on track to defeat Republican candidate Roger Marshall, who garnered 44.9%, according to NBC News.

Kansas has not produced a Democratic senator since 1932.

Hamilton's potential victory is expected to be recorded as an upset in U.S. political history.

If Hamilton solidifies his victory as projected by NBC, it not only means defeating the incumbent Senator Marshall, but it is also expected to deal a significant political blow to President Donald Trump.

In Iowa, another battleground state, with 89.7% of the vote counted, Democratic candidate Josh Tureck was projected to win with 50.9% of the vote, defeating Republican candidate Ashley Hinson, who received 46.0%.

Among the seven battleground states designated late in the election, the Democratic Party has won all four where outcomes have been projected so far: Texas, Ohio, Kansas, and Iowa.

NBC reported that the Democrats are expected to secure a Senate majority with 51 seats, having flipped six seats held by incumbents from the Republican Party, including not only North Carolina, which was rated as leaning Democratic, but also South Carolina.
