WASHINGTON (AP) - Democrats in Iowa are trying to weaken Republican Mitt Romney in advance of Tuesday's lead-off presidential caucuses as polls show the former Massachusetts governor amassing support.
Democrats were dispatching party leaders and surrogates to Iowa to assail the Republican field while paying close attention to Romney, who leads in national polls and in Iowa.
President Barack Obama is expected to compete for Iowa next fall. He won there in 2008. He planned to address Democratic caucus attendees by web video Tuesday night.
The Democratic National Committee has held events with a union official who was laid off by a company that Romney's former firm, Bain Capital, restructured more than a decade ago. The worker, Randy Johnson, argued that the layoffs show that Romney doesn't understand working people's needs.
