Aug. 15 (Bloomberg) –- U.S. Senator Marco Rubio, a Florida Republican, speaks in Gainesville, Florida, about his support for an overhaul of federal immigration laws.
Rubio's role as co-author of the immigration-law rewrite has cooled Republicans on the Tea Party hero. Rubio, 42, who's said he’ll decide next year whether to run for president, fell from first to fifth in a poll of nine potential Republican candidates in Iowa, the state that holds the first contest every four years.
