Because in 2010, the repubs won a blow out across the nation, we got control most of the redistricting for the 2012 election.
In 2012, more voters in Ohio voted for the democrat congressmen, but the gop won 11 out of 16 seats.
This was also true nationwide as the dems got more votes, but we still held the house.
Until 2022, it will be almost impossible for the dems to control the house.
It was the same in 1984. The repubs won more votes, but the dems had an overwhelming majority in the house of reps due to gerrymandering.
Bottomline: if you are a political party, you do not want to get blown out in 2010 or 2020 or you will suffer the consequences.
The Ohio House and Ohio Senate are similarly gerrymandered to shut out the dems for the next decade. Of course the dems did it to us in IL, MD and CA.
Texas newspapers never complained when Dallas-area Dem congressman Marty Frost got together with Gov. Ann Richards in 1991 to gerrymander hell out of the Texas Lege and the U.S. Congressional Districts.
But when Tom Delay turned the tables in 2001, hell wouldn't hold the whining and sniveling from the JournoRats, and they universally called for superpartisan 'Rat prosecutor Ronnie Earle in Austin (who once prosecuted Kay Bailey Hutchison because some of her staffers had made political-campaign calls on her state telephones) to prosecute Delay and send him to prison -- for whatever, because Delay hurt their politics. So he did.
They're still crying about redistricting, and suing hell out of the State every chance they get. The Supreme Court last spring told them to knock it off, but they went right back to court -- and delayed Texas's primary until the campaign for the nomination was over.
Let 'em cry, they deserve it now. Screw 'em.
