Lawmakers will soon begin to redraw legislative districts based on new census data. Many pundits have said this year’s elections have given Republicans an edge in redistricting, because the party has been voted into power in many areas.

But the Fix says the GOP’s wide majority in the House is evidence of the opposite:

In fact, they’ve got their work cut out for them in even keeping their current majorities in many states.

The Republican majority, which will be 47 seats when the new Congress is sworn in next month, will be bigger than at any point in the last 60 years. That means the party is already stretched pretty thin when it comes to the districts it holds.

Adding seats to that map is very difficult — even in many of the states where Republicans control the redistricting process and will be drawing the lines.
