Texas: Mapmakers built the GOP’s political house on high ground | The Texas Tribune

Texas’ gerrymanders are the political equivalent of putting houses on stilts to keep them safe from flooding. Democratic hopes for a “blue wave” that would lift some of their candidates into statewide office and reduce their disadvantages in the congressional delegation and the statehouse aren’t completely out of line. Presidents’ political parties often have trouble in midterm elections. It’s just that Republicans in Texas drew maps in 2011 — since modified by the federal courts but still being litigated — that protect the party’s officeholders from most changes in public sentiment.
