Washington (CNN) -- Wendy Davis is attacking her partially paralyzed Republican opponent Greg Abbott in the Texas governor's race -- with an ad that features an empty wheelchair. "A tree fell on Greg Abbott. He sued and got millions. Since then, he's spent his career working against other victims," a narrator says of the wheelchair-bound Abbott. The spot is a Hail Mary from the Democratic state senator who is badly trailing in the race. Abbott led Davis 54% to 40% in a recent CBS/New York Times/YouGov poll, and there are few signs she's likely to close that gap before the November 4 election.
