Democrat Tim Ryan and Republicans Bill Johnson and Steve LaTourette are positioned well to hold onto their congressional seats next election.
A report by the Cleveland Plain Dealer shows that in Ryan's newly-drawn 13th district, about 62 percent voted Democrat in the 2008 presidential election and in last year's elections for governor, secretary of state and auditor.
That same review using data from the Ohio Secretary of State's Office and the Ohio Campaign for Accountable Redistricting shows that in Johnson's 6th District, nearly 54 percent sided with the GOP, and in LaTourette's 14th District, slightly more than 54 percent voted Republican.
The new map that shrinks Ohio's congressional districts from 18 to 16 was approved by the Republican-controlled House Thursday by a vote of 56 to 36 and it's expected to receive approval in the also GOP-controlled Senate sometime this week.
The loss in congressional representation is due to Ohio's population loss.
Ryan gained some ground in Mahoning and Summit counties and even a corner section of Stark County, but lost some territory in northern Trumbull County and also in Portage County.
Johnson's sprawling 6th District includes the addition of three whole counties and parts of two others; he loses portions of Mahoning and Athens, but he maintains Columbiana County - the most populous county - much to the delight of Columbiana County GOP Chairman Dave Johnson.
And LaTourette's 14th District picks up more of Trumbull County's northern tier, plus the Republican gains more ground in Portage, Cuyahoga and Summit counties.
Ryan kept the core of his district in Warren and Youngstown and he got stronger, with the added communities in Mahoning County, which include Boardman and Poland.
''The Mahoning Valley did well. Both of our representatives probably will be able to hold their seats,'' Paul Sracic, chair of Youngstown State University's political science department, said.
And so likely will LaTourette.
LaTourette has won each of the last general elections by about 20 percent. In 2010, it was 33 percent; 2008, 19 percent; and 2006, 18 percent.
Ryan's figures are more impressive with winning margins of nearly 24 percent last year; more than 55 percent in 2008; and more than 60 percent in 2006.
The Democratic and Republican parties in Mahoning County are holding fundraisers this week.
On Monday, Democrats will host special guest Ed Fitzgerald, Cuyahoga County executive, at the annual chairman's dinner at Antone's Banquet Center in Boardman.
Party Chairman David Betras said the money raised will be used to battle Issue 2, the referendum on Ohio's new collective bargaining law on the Nov. 8 ballot.
On Wednesday, the Republican party is holding a fall dinner at the Georgetown Banquet Center, also in Boardman. Entertainment will be provided by the Seraphim Chorus and the program is hosted by attorney Staughton Lynd.
