Latest ComRes and Opinium polls
The monthly online ComRes poll for the Independent on Sunday and Sunday Mirror is out tonight and has topline figures of CON 31%(-1), LAB 34%(nc), LDEM 9%(+2), UKIP 17%(-1), GRN 4%. Changes are from ComRes's last poll a month ago, and don't show any significant movement.
I sometimes see people asking if asking "if there was an election tomorrow" produces different results from "the next election in May 2015". ComRes did a split sample this month asking and asked the two halves with the two different wordings: there was no significant difference. Asking about next May produced a Tory score one point higher, UKIP two points lower... but these differences could easily be normal sample error (especially given they were only to half sized samples).
If you really wanted to test if the different wordings had any effect you'd need to test on a much bigger scale to differentiate any effect from normal sample error, especially since any difference is likely to be small. Personally I doubt it does make any difference, but would always ask "tomorrow" on principle, just to emphasize that a poll really is a snapshot of opinion NOW, not a prediction of opinion next year.
Opinium's fortnightly poll in the Observer is also out tonight, and they have toplines of CON 30%(+1), LAB 34%(-1), LDEM 9%(+2), UKIP 17%(-1).
