SACRAMENTO, Calif. AP – When people sign up for Twitter, the popular social-networking site presents a list of suggested users to follow, driving significant traffic to sports figures, celebrities, politicians and other prominent posters.

In California, the list has attracted the attention of political watchdogs because it apparently favors Democrats over Republicans in next year’s race for governor. That raises questions about whether Twitter should change its policy at a time when the site is catching on as a popular recruiting tool for candidates.
