State Sen. Wendy Davis, the Democrats' best hope to run for Texas governor, said this week she is postponing the announcement of her decision so she can help care for her sick father. “I had hoped to make public my decision about that next week, but with everything that’s going on with my dad, I won’t be doing that,” she said. “It’s likely it will be late September before I do.” Davis’ father, Jerry Russell, has been in critical condition at Texas Health Harris Methodist Hospital in Fort Worth following complications from abdominal surgery. In a Facebook post, Davis said Russell, who has been battling pneumonia, was “continuing to show small but positive steps toward improvement” but was “not out of the woods” yet.
