A trio of conservative groups on Saturday announced plans to spend millions of dollars in support of Judge Amy Coney Barrett’s nomination to the Supreme Court, previewing what will be an expensive and intense confirmation battle in the weeks before Election Day.

Judicial Crisis Network, which focuses on the nomination and confirmation of conservative judges, said it expects to spend at least $10 million in support of Barrett. The group already launched a $2.2 million campaign urging swing state Republicans to move forward with Barrett’s confirmation despite it coming so close to the election.

The organization on Saturday unveiled a $3 million ad buy that focuses on her qualifications from the court. The ads will air in Colorado, Iowa, Maine, North Carolina, Utah, and Washington D.C.

“Justice Ginsburg was confirmed in 42 days, Justice O’Connor in 33, and both confirmations were nearly unanimous,” Carrie Severino, president of Judicial Crisis Network, said in a statement. “But Democrats won’t be able to bring themselves to support Judge Barrett because they are beholden to leftwing extremists who want to pack the Supreme Court and defund the police while our cities burn.”

Susan B. Anthony List, a group that backs pro-life judges and political candidates, plans to invest seven figures in support of Barrett’s confirmation. The organization on Saturday announced a six-figure ad digital ad campaign that highlights her pro-life views.

Americans For Prosperity, meanwhile, will target Alabama, Alaska, Arizona, Colorado, Georgia, Iowa, Maine, North Carolina, South Carolina, Utah, and West Virginia with ads urging senators to confirm Barrett.

“Any senator, of any party, who wants a Supreme Court that puts the Constitution first, interprets the law as written, and protects our freedoms should be thrilled by Judge Amy Coney Barretts nomination and commit to her prompt confirmation,” said Casey Mattox, Vice President for Legal and Judicial Strategy at Americans for Prosperity.

Conservative groups spent roughly $16 million in support of Kavanaugh’s nomination in 2018, which played out over roughly three months.

Barrett’s confirmation is likely to be a sprint as Republicans hope to hold a final vote on her nomination before Nov. 3.

Instead, Democrats are expected to focus on arguing that Barrett’s confirmation would pose a threat to health care accessibility and reproductive rights.

Demand Justice, a progressive group with a focus on the judiciary, is planning to spend $10 million on an ad campaign aimed opposing Barrett’s nomination.
