It'd be interesting to see how the polls change after this policy blitz.
I've been trying to emulate how FiveThirtyEight did their (albeit unsuccessful) US polling.
With weighted polls (based on historical accuracy), historic data, and betting odds I currently have this...
CON: 43%
LAB: 36%
LIBD: 8%
UKIP: 5%
My swingometer is still really basic (a LibreOffice Calc spreadsheet with a few functions and macros), but I currently have the seat count at...
CON: +5 gains = 335 seats
LAB: -1 loss = 232 seats
LIBD: -3 losses = 5 seats
UKIP: No change = 0 seats
20 majority for the Tories.
Still plenty to play for.
