U.S. Sen. Elizabeth Warren, who is campaigning for her third term in office, has raised concerns about the implications of Republican control of the Senate. Republican nominee John Deaton won the party’s primary on Tuesday and will be Warren’s opponent for the November general election.

“If they get John Deaton elected, the consequence of that will be in a 50-50 Senate that the Republicans take control,” Warren asserted on Boston Public Radio on Thursday.

Currently, Democrats hold 51 seats, while Republicans have 49. More than 30 Senate seats are up for grabs in the general election, the majority of which are currently held by Democrats.

Warren emphasized that Republican control would lead to the nomination and confirmation of younger conservative justices to the Supreme Court, potentially replacing the three oldest members.

“The Republican efforts in the House and the Senate to have a nationwide abortion ban will have new life. It means cuts to Medicare and Social Security will be back on the table. And it means that billionaires will get even more tax cuts,” Warren added.

Warren criticized cryptocurrency advocate Deaton’s path to the nomination, given his campaign was significantly funded by cryptocurrency billionaires.

“The other two Republicans didn’t have that kind of money. So now he’s got that seat,” Warren said. “That means that they will get rid of someone who is not always on board with the things that they want to be able to do.”

Previously, Deaton has accused Warren of being out of touch with working families. “Warren’s great at fighting against the wealthy and the rich. That is not the same as fighting for the poor and for working families,” he said in July.

Warren defended her record on Thursday. “My whole life’s work has been about how to help working families. Middle-class families survive in a swimming pool that is increasingly full of sharks.”

She noted her efforts to make hearing aids more affordable and to protect consumers from overdraft fees protect consumers from overdraft fees imposed by big banks.

Warren also reaffirmed her commitment to protecting Medicare and Social Security, criticizing Republican attempts to cut these vital programs. “Every time we go into this fight, the Republicans not only do not want us to expand Medicare coverage. … Donald Trump put into every one of his four budgets that he would cut Social Security and Medicare.”

“We lose one seat as Democrats and the Republicans take over, and we’ve lost it all,” Warren said.
