The federal Democratic Congressional Campaign Committee has set its sights on three Texas districts currently held by Republicans, including Harris Co.-based CD7, which has been represented by a Republican since 1967. Only the U.S. Senate seat occupied by John Cornyn has been held by Republicans for a longer period (1961-present).

In November, U.S. Rep. John Culberson (R-Houston) won re-election by 12 percentage points, his smallest margin of victory in his nine elections to Congress. His only other close race was in 2008, when the combination of a well-financed opponent and a national tide created by enthusiasm for Barack Obama held Culberson just below 56% of the vote.

Democrats can see some reasons for optimism in CD7 based on the 2016 results.
