WASHINGTON (AP) — Hillary Rodham Clinton promptly set off on the campaign trail after making her long awaited entry into the 2016 presidential race, and her potential Republican rivals wasted no time unleashing blistering criticism of the former secretary of state.
Clinton, seeking to become America's first female president, announced her candidacy Sunday and left on a trip from her New York home to Iowa, the Midwestern state that kicks off the long, state-by-state contest for the Democratic nomination.
In a video message announcing her candidacy, Clinton promised to serve as the "champion" of everyday Americans in a country with growing income inequality.
Clinton appears unlikely to face a formidable Democratic opponent in the primary elections. Should she win the nomination, Clinton would face the winner of a crowded Republican primary field that could feature as many as two dozen candidates.
Already the Republican Party is treating her as the Democratic nominee.
Announcing his own 2016 campaign to top donors Monday, Florida Sen. Marco Rubio branded the former first lady, senator and secretary of state as "a leader from yesterday who wants to take us back to yesterday."
Kentucky Sen. Rand Paul, another declared candidate, put Clinton at the center of his first TV ad, titled "Liberty, not Hillary."
Some Republicans sought to make foreign policy an issue at a time when the Obama administration is negotiating a nuclear deal with Iran and moving to restore diplomatic relations with Cuba.
"We must do better than the Obama-Clinton foreign policy that has damaged relationships with our allies and emboldened our enemies," said former Florida Gov. Jeb Bush in his own online video Sunday. Bush, the brother and son of former presidents is widely expected to join the race for the Republican nomination.
Republicans have also jumped on Clinton's use of a personal rather than a government email account and a server located in her home while she was secretary of state. They have also raised questions about donations from foreign governments to the Clinton family's foundation.
Unlike eight years ago, when she ran and lost the Democratic nomination to Obama, Clinton and her personal history weren't the focus of the first message of her campaign Sunday. She made no mention of her time in the Senate and her four years as secretary of state, or her potential to make history as the nation's first female president.
Instead, the video is a collection of voters talking about their lives, their plans and aspirations for the future. Everyday Americans need a champion, and I want to be that champion," Clinton said.
Clinton hopes to avoid the same stumbles in 2008, when she entered the race as a heavy favorite only to be upset by Obama in Iowa.
Her first campaign event is Tuesday.
The road trip was Clinton's idea, aides said.
"When Hillary first told us that she was ready to hit the road for Iowa, we literally looked at her and said, 'Seriously?' And she said, 'Seriously,'" said longtime aide Huma Abedin in a conference call with Clinton alumni.
A Clinton aide said the van is nicknamed "Scooby" after the van in the 1970s animated television show, "The Scooby Doo Show."
The 67-year-old Clinton brings a long public record to her second bid for the White House, a history that will both help and hurt her candidacy. Republicans were already pushing a message that seeks to attach her to the scandalous upheavals of her husband Bill Clinton's two-term presidency in the 1990s.
Understanding that, her staff has said she intends to cast herself as a "tenacious fighter" determined to block the growing power of an increasingly right-wing Republican Party that has sought to block Obama's agenda and now controls both chambers of Congress.
