UNITED STATES, July 21 ---- TPresident Barack Obama sought a boost for his campaign in the crucial state of Florida on Thursday, amid new signs that voters are increasingly dissatisfied with his handling of the U.S. economy and questions about whether his attacks on Republican Mitt Romney are resonating.

Kicking off a two-day swing through this politically divided state, Obama tried to shore up his support with senior citizens and continued to cast Romney as a defender of the rich at the expense of the middle class.

His trip came a few hours after two new polls suggested that even after several weeks in which his campaign has controlled the narrative of the presidential race, voters' concerns about the economy are dragging down Obama's support for the November 6 election.
