Senator Elizabeth Warren (D., Mass.) went to the scene of Barack Obama’s first victory over Hillary Clinton to rally the party faithful on behalf of Representative Bruce Braley, the Democratic nominee to replace retiring Senator Tom Harkin (D., Iowa).

“The audience, which the Braley campaign estimated to be around 600, cheered zestily” for Warren, according to the Des Moines Register. “On her first visit to first-in-the-nation Iowa of the 2016 presidential election cycle, Warren shared some of her personal history, but focused most of her speech on the benefits of government spending on education, infrastructure and research a generation ago.”

Warren launched a broadside against Republicans that she could redirect against Hillary Clinton with just light editing.

“In a passion-filled liberal stemwinder, Elizabeth Warren shouted down the GOP agenda, which she said is all about cutbacks and doing the bidding of millionaires, and warned the crowd that Iowa’s tight U.S. Senate race could come down to how hard Democratic activists work,” the paper reports.

Progressive activists have launched a “Ready for Warren” draft movement to rival the “Ready for Hillary” operation that has been preparing for Clinton’s expected 2016 run. Warren had her lawyers send a letter to the FEC opposing the organization.

“The Senator has not, and does not, explicitly or implicitly, authorize, endorse, or otherwise approve of the organization’s formation or activities,” the August letter says. “To the contrary, Senator Warren has publicly announced that she is not running for President in 2016. Instead, the Senator hopes this organization will focus its attention and energy on maintaining Democratic control of the US Senate and not confuse donors about a non-existent run for President.”

In 2006, then-Senator Obama told NBC’s Tim Russert that he would not run for president. “I will serve out my full six-year term,” Obama said. ”You know, Tim, if you get asked enough, sooner or later you get weary and you start looking for new ways of saying things, but my thinking has not changed.”

Obama upset Clinton in the 2008 Iowa Democratic caucuses.
