Declining to endorse in the Arizona Senate GOP primary, Joe the Plumber said he doesn't want to "create a lot of drama."
Samuel "Joe" Wurzelbacher was in Phoenix last weekend for a pair of anti-tax rallies at the state Capitol. He overlapped on both occasions with J.D. Hayworth, McCain's primary opponent, but he didn't endorse the former congressman.
Still, the conservative activist was willing to criticize the Arizona senator's stance on immigration and border security.
"It's supposed to be a closed border. Why don't you uphold the law instead of trying to change it?" he told FoxNews.com. "McCain's been a senator for a long time and he's failed in his duties."
But Wurzelbacher insisted he won't back Hayworth in the primary. "I don't want to cloud the issue and create a lot of drama," he said.
