Venus's solar tidal drag on the solid body is enough to have modified the planet's spin rate, but as I recall, models have indicated despinning from solid body tide during the age of the solar system is unlikely.
There are also significant thermally driven and gravitational tides in the atmosphere, some models have indicated these have contributed to the non-zero spin rate of the planet. The really BIZARRE and unexplanable thing is that Venus is close to being tidally locked with the same hemisphere facing Earth every conjunction. It's not exact, but it is very close. No tidal model involving Earth comes anywhere near able to explain that and it may be pure cooincidence. Note: All this info is off the top of my head from old studies.
