MIAMI, the United States, June 15 (Xinhua) -- Former Florida Governor Jeb Bush on Monday joined an already crowded Republican presidential field and vowed to fix a "dysfunctional Washington."

Though a Republican establishment candidate, Bush, 62, joined other Republican hopefuls to distance himself from politics in Washington and blamed the U.S. government for problems facing the country.

"We'll take Washington -- the static capital of this dynamic country -- and turn it out of the business of causing problems," Bush told a rally at Miami-Dade College, Kendall campus, in his home state of Florida, where he was a two-term governor.

Even before his Monday announcement, Bush, the son and brother of former U.S. presidents, had worked hard to prove that he was his own man in terms of foreign policy.

On Sunday, the Bush campaign team released a new logo "Jeb!" without mentioning the surname, which is expected to be his largest asset and biggest problem simultaneously in the next 17 months.

Meanwhile, though regarded widely by many as the front-runner in the Republican field, latest polls show that Bush fares no better than other Republican candidates against Hillary Clinton, the undisputable front-runner in the Democratic Party.
