The Democratic Party of Arizona has censured centrist Sen. Kyrsten Sinema for her opposition to filibuster reform.

The Democratic Party of Sinema’s home state blasted what it said was her failure to further the protection of voting rights nationwide. Sinema and West Virginian Sen. Joe Manchin were the only two Democrats to join with Senate Republicans in opposing the rule change Wednesday, which would have allowed their party to push through two bills expanding federal oversight of elections over the objections of the minority party.
