The GOP is a 'House Divided' and as such, they are enduring many self-inflicted wounds during the run-up to the 2018 mid-term elections:
Title: "What to do about the GOP's self-inflicted wounds? | Lowman S. Henry"
http://www.pennlive.com/opinion/2018/04/what_to_do_about_the_gops_self.htmlExtract: "There is no problem in which the Republican Party finds itself that it can't make worse. Such is the case with GOP efforts to defend an increasingly frail majority in the United States House of Representatives.
…
At the moment, it appears the party is doing nothing right and good ole Penn's Woods has contributed mightily to their woes.
Let us count the ways.
Tilt the Playing Field: Years ago national Democrats realized they had no chance of regaining control of congress given the redistricting plans implemented in the several states.
Rather than wait until 2021 and the next scheduled round of redistricting they set about challenging existing plans in key states such as Wisconsin, North Carolina and, yes, Pennsylvania. To ensure success the Democrats and their labor union allies essentially purchased control of the state Supreme Court.
…
Special Election Misfire: When a scandal forced the resignation of suburban Pittsburgh Congressman Tim Murphy it looked like a sure bet Republicans would retain the seat.
President Trump carried the district by nearly 20 percentage points in 2016.
State Rep. Rick Saccone, R-Allegheny, was selected as the Republican nominee and proved to be a less than stellar campaigner.
…
A House Divided: Congressional Republicans have spent more time fighting each other than engaging the Democrats. On any major vote not a single Democrat will break ranks, but Republicans couldn't agree on the color of the White House.
…
The Costello Cop Out: Retirements, including the high profile decision by House Speaker Paul Ryan to end his congressional career, further add to the steep hill the GOP must climb.
To date, 40 Republican congressmen are either retiring or running for higher office. That is far above the historic average of 25 retirements per cycle. Five Pennsylvania Republican congressmen have announced their retirements, the latest being U.S. Rep. Ryan Costello of Chester County.
…
Thus Pennsylvania has become the Keystone state for Democratic efforts to reclaim control of the U.S. House of Representatives.
And they are doing so with significant help from the GOP itself."
