State Rep. Ross Spano, R-Dover, will announce today that he'll run for the District 15 U. S. House seat being vacated by Dennis Ross.

Spano, 51, an attorney, is currently in his third term in the state House and one of four Republican candidates for state attorney general.

Sources close to his campaign said he'll announce the switch to the U.S. House race today.

Ross, a Lakeland Republican, surprised the Tampa Bay area political world last week by announcing he won't seek what likely would have been an easy re-election to his congressional seat.

But Spano is only one of a number of prominent East Hillsborough and Polk County Republicans considering a run to replace Ross, including state Sen. Tom Lee, R-Thonotosassa.

Ross's last-minute resignation left comparatively little time for Lee and others to jockey into position for the race. The qualifying period for federal offices is April 30-May 4.

District 15 includes northeastern Hillsborough County and parts of Polk and Lake counties.
