Source: Clinton to Announce on Sunday

When, where, how? A source close to Hillary Clinton's campaign tells the Guardian she will tell the world of her intention to run for president on Sunday at noon Eastern, on Twitter, while on her way from New York to Iowa. The Twitter announcement will be followed by a video and an email, says the source, and Iowa will be followed by visits to other early primary states. Clinton's rep wouldn't comment, but another source confirms to the Guardian that she'll soon be in Iowa. The New York Daily News also has a source saying Clinton will announce Sunday, and Reuters says "a variety of sources in the Clinton orbit" confirm an announcement is imminent, though none would pin it to Sunday.

Clinton has been building up her operation and staff in Iowa while leasing space for what's thought to be her campaign headquarters in Brooklyn. Contender Rand Paul will be in Iowa today, along with former Democratic senator Jim Webb, who has launched a presidential exploratory committee. Ted Cruz, also an official presidential contender, was in the state yesterday. Marco Rubio is expected to announce his own presidential campaign Monday from Miami. Meanwhile, a recent Quinnipiac University poll that looks at Clinton's lead over potential big-name Republican contenders suggests her support is fading a bit, at least in Colorado and Iowa, but has grown in Virginia, the Washington Post reports.
