Vermont‘s representation in the US Senate is all set to change for the first time in 15 years. Peter Welch advanced to the midterms with the Democratic nomination and will face Gerald Malloy, a Republican who won his primary.

Peter Welch, who is currently a US Representative, gave up his Congressional seat to contest the Senate election. He is attempting to fill in for Patrick Leahy, a veteran Senator who announced his retirement last year.

Welch easily defeated two little-known candidates to move on to the general election in November. During the years he has been in Congress, Welch has been one of Vermont’s top vote-getters and would be an odds-on favorite to win the general election.

The Republican primary was won by Gerald Malloy, who secured more than 43% votes. Malloy defeated little-known candidates like Christina Nolan and Myers Mermel. The general elections ballot for Vermont’s Senate seat will also see Martha Abbott, the progressive primary who was unchallenged.

Peter Welch’s participation in the Senate race left Vermont’s only House of Representatives up for grabs. In Tuesday’s primary election, state Senate leader Becca Balint won the Democratic nomination for the position.

In deep blue Vermont, it’s likely the Democratic candidate will also clinch the general election in November. A win by Balint, who is white, would help erase what some consider to be the blot on the liberal state’s reputation of only being represented by white men.

Vermont has been represented in Congress by white men ever since it became the 14th state to join the union in 1791, news agency Associated Press reported. If she wins, Balint will not only be the first woman to represent Vermont in Congress, but the first openly gay person, too.
