2028 United States Senate Elections (Pear's Future III)

The 2028 United States Senate Elections occurred with the victory of Ron Desantis as President of the United States. Desantis' win over incumbent Democrat Kamala Harris helped the Republicans down ballot, as Republican across the nation did surprisingly well. Republicans, lead by Senator John Thune of South Dakota, went onto to hold their majority in the Senate over the Democrats, lead by retiring Senator Chuck Schumer of New York. Schumer was replaced as majority leader by Jeff Merkley of Oregon.

Following the 2026 Senate Elections, Republicans held a 53-47 seat majority in the Senate. However, when Senator Cory Booker of New Jersey resigned to become Vice President of the United States, Republican Governor Jack Ciaterelli had appointed Republican Simon Fraser to replace him, with Fraser winning the special election in November 2027 to serve out the rest of Booker's term. This meant that Republicans now held a 54-46 Seat majority in the Senate. Despite this, they continued to make gains, winning two open seats in Pennsylvania and New Hampshire, largely helped by Ron Desantis winning these states in the Presidential Election. Democrats on the other hand, were able to win the seat of Wisconsin, defeating incumbent Senator Ron Johnson. This was the first seat that Democrats had gained since John Fetterman won Pennsylvania 6 years back.

Following the elections, Republicans had a 55-45 majority in the Senate. However, a special election held in Iowa in November of 2029 following the resignation of Senator Joni Ernst triggered a special election that was won by Democrat Rob Sand. This meant that control later became 54-46 again until the 2030 Senate Elections.

Arizona
Incumbent Senator Mark Kelly ran for re-election to a second full term in office. Kelly faced former venture capitalist Blake Masters in a rematch of the 2022 elections. Although Arizona was seen as a swing state in the simultaneous Presidential election, Kelly's popularity made him the favourite for re-election. Masters, who had ran a conservative campaign in 2022, ran on a more moderate platform, which was seen as upsetting to some voters who found him as a grifter. Ultimately, Kelly decisively won the election, winning 52.5% of the vote to Master's 45.9%, despite Ron Desantis carrying Arizona by 4.2% on the Presidential level.

Incumbent Senator Marco Rubio was originally running for re-election, but later decided that he would not run for another term in office. Repbublican Mayor Francis Suarez won the primary very narrowly in a field of 9 other candidates, while Democrats nominated former state representative Anna Eskamani. As former Governor Ron Desantis was running for President on the same ticket, Republicans were expected to easily win this once swing state.

Georgia
Incumbent Senator Raphael Warnock did not run for a second full term in office. Democrat George Douglas won his parties' primary in a massive upset, while Republicans nominated former U.S. Senator Kelly Loeffler, who was appointed to this seat 2019 and lost re-election to Warnock in the 2021 runoff. This race was expected to be competitive, as polls showed a close race, as with the simultaneous Presidential Election. Although Ron Desantis narrowly carried Georgia in the Presidential election, Douglas lead Loeffler in the first round, although he failed to win more than 50% of the vote, sending the race to a runoff. As polls showed the race leaning towards Douglas favor, Republicans were unable to keep up and Loeffler lost by a record 9 points.

Democratic Primary
Although four Democrats were given ballot access in the primary, only two were considered serious contenders for the nomination. Stacey Abrams, the well known former 2-time gubernatorial candidate, was the early front runner, leading with over 61% of the vote in early polls. Her main rival was George Douglas, who had ran a serious primary challenge against Senator Jon Ossoff 2 years back. Although Abrams had most of the state Democratic party backing up her nomination, including Georgia's other Senator Jon Ossoff, Douglas gained serious support from National Democrats, including Chair of the National Democratic Senatorial Committee Tim Kaine. Abrams attacked Douglas for his national support by portraying him as a man who is supported by out of state millionaires with no concern for his state, while Douglas attacked Abrams for losing two gubernatorial races already, saying that he had the better chance to win. Although polls in fall had the two tied in support, Douglas enjoyed a good debate performance and his poll numbers increased, allowing him to win a comfortable victory over Abrams. After the primary, Abrams says she was "screwed by National Democrats who don't want a black woman in the Senate", and refused to endorse Douglas in the general election.

Republican Primary
The original frontrunner for the Republican primary was former Representative and Vice Presidential Nominee Marjorie Taylor Greene, who had lost to Jon Ossoff in 2 years earlier for Georgia's other Senate seat. Many Republicans did not want to challenge Greene, who had a lot of fundraising and name recognition from her past campaigns. As such, Greene faced only token opposition and was the presumptive nominee. However, Greene ended her campaign for the Senate and instead ran for President of the United States before withdrawing from the primaries as well. Following her withdrawal, several Republican candidates jumped into the race, of which the frontrunner became former Senator Kelly Loeffler.
