Agree with you its not a normal thing for die hard Labour supports to switch to the Torys( i did say i might) but only for the reason that i actually think May is the only one to get Brexit done(not saying she will be great, but have no confidence in any of the others) believe me there are plenty of others like me thinking the same, i mentioned this on another thread, theres definitely a shift of support(if they are to be believed that is!)
There is also the Zero hours ban Labour may bring in(which i like) and defense feels very dodgy with Corbyn(and the man with his policy's does count for me) As for Lib Dems done a tactical vote with them once to try kick Tory candidate out but wasted, the time of the u-turn on University fees. Also just not keen on them/policy's.
Am more likely if foxhunting does become an issue vote Green or a decent independent, but Brexit whether you like it or not, is a big issue to(for me anyway) but i absolutely hate foxhunting to....never ends does it with twists and turns
