Welcome to the new Pennsylvania which will look like it is trending Republican for a decade.

Real Clear Politics' Sean Trende is already calling it the "gerrymander of the decade."

Republicans who seized control of the Pennsylvania legislature, have redrawn their congressional districts such that there are 12 solidly Republican seats out of 19 districts in a state that has 2-3 percent more Democrats than Republicans.

The different colors in the map above represent the newly redrawn congressional districts, and the blue lines represent actual counties.

The redistricting plan is expected to pass this week and it will have consequences. It will force Democratic Reps. Jason Altmire and Mark Critz into a primary in a new district that is trending Republican. It dramatically helps Republican freshmen like Lou Barletta and Tom Marino by eliminating urban areas from their districts and extending their territory into more rural area.
