MIAMI -- Alleging that the Republican Party is resorting to dirty tricks to intimidate voters, Janet Reno and U.S. Rep. Carrie Meek filed suit Thursday to prevent a Republican political-action committee from stationing more than 450 poll watchers at heavily Democratic precincts in Miami-Dade County polls on Election Day. The suit, filed in Miami-Dade Circuit Court, names Miami-Dade Supervisor of Elections David Leahy, the county's Republican Party and the Emergency Committee to Stop Bill McBride as defendants. "The emergency is they want to create disruptions at the polls," said Joe Geller, counsel for the Miami-Dade Democratic Executive Committee.
