From KERA:
When Republican Congressman Joe Barton announced he’d retire after 34 years in the House, 16 Democratic and Republican candidates campaigned to win the open seat.
Now, the Democratic field has narrowed to two.
In the March primary, Ruby Faye Woolridge came out in the lead, but just barely. Nineteen votes separated her from Jana Lynne Sanchez. The two Democrats are challenging each other again in the May 22 runoff.
