Serena Williams would vote for Barack Obama if she could. Don’t even ask Venus Williams what her political leanings are.

The Williams sisters, vocal on so many issues from fashion to gender equality and equal pay for women, say they’re not allowed to vote because of their religion. The sisters, who have 14 Grand Slam singles titles between them and are among the most recognizable athletes in sports, are Jehovah’s Witnesses.

After their first-round wins at Wimbledon, both were asked about the Nov. 4 presidential election.

"I feel that what I do in tennis isn’t really political," Venus said after her 7-6 (5), 6-1 win over British wild card entry Naomi Cavaday on Tuesday. The work she does for UNESCO and other agencies was about helping people, she said, "I don’t see it as political. I don’t vote."

Younger sister Serena said she was "excited to see Obama out there doing his thing."

"I’m a Jehovah’s Witness, so I don’t get involved in politics. We stay neutral. We don’t vote," she said. "So I’m not going to necessarily go out and vote for him. I would if it wasn’t for my religion."
