For our list of the most competitive races in Texas congressional and legislative elections, we lifted the color scheme from the inventors of the federal terror watch, ranking races by the threat to each incumbent, to the incumbent party, or just by the level of interest and heat generated.

Yellow means there's trouble on the sidewalk. Orange is trouble on the front porch. Red is trouble walking in the door.

Incumbents' names are bolded. This is certainly and intentionally subject to argument, and we'll revise and adjust and argue and debate as the March 1 primary approaches. Let us know what you think.

Changes this week: We added HD-47 to the list and put it in orange, added HD-113 and CD-32 to the list and labeled them yellow, and raised HD-14 to red.
