Congressman Joaquin Castro may be planning a Senate run for next year, according to his brother, former HUD Secretary Julian Castro:
Democrats have a difficult map in 2018, playing defense in 25 seats, compared to the GOP’s 7. In addition to that, Democrats haven’t won a statewide office in Texas since 1994, but depending on the political and economic dynamics of the country in 18 months, and the fact that Senator Ted Cruz has burned a lot of bridges even within his own party, this could be a long shot pickup opportunity for Senate Democrats in 2018.
