Results of the polls - races 5, 6 and 7

Very varied polls for the last three grand prix, but no really surprizes.
Let us have a look at the results:

Before Race 5 - Spain
Who will remain at 0 point at the end of the season?
1. G. Fisichella 5 (50%)
2. K. Nakajima 3 (30%)
3. A. Sutil 2 (20%)
4. N. Piquet, R. Kubica, and none 1 (10%)

Notice that multiple answers were possible.

Before Race 6 - Monaco
Which F1 team will be World Champion of the Constructors?
1. Brawn GP 6 (54%)
2. Red Bull 3 (27%)
3. McLaren and Ferrari 1 (9%)
5. Toyota, another team 0 (0%)

Before Race 7 - Turkey
Who will be world champion ?
1. J. Button 6 (75%)
2. R. Barrichello, S. Vettel 1 (12%)
4. L. Hamilton, F. Massa, another driver 0 (0%)

This question was posed for the 2nd time, following poll #1.
Remember the result here. If "Jenson Button" now equals "another Driver" in poll #1, it seems that 2 voters may have predicted his current domination.

Thank you for your participation.
