Not a single Republican senator signed on to letters sent this week by 50 senators to the NFL commissioner demanding a name change for the Washington Redskins.

But no one asked them until the letter was already sent. […]

One Republican — Sen. John McCain (R-Ariz.), whose state has a significant portion of Native Americans — said he “probably” would have added his signature to the letter if he had been asked. That would have elevated the stature of the Democrats’ initiative by making it both bipartisan and endorsed by the GOP’s 2008 presidential nominee. McCain has joined Democrats on some social issues recently, advocating to end workplace discrimination based on sexuality and urging his governor to veto a bill that would have allowed businesses to deny service to gay customers.

“They didn’t ask,” McCain said, confirming he still opposed the “Redskins” moniker for the team. “It’s offensive to our Native Americans.”
