Kantar and YouGov show the race narrowing...
Two polls are out tonight. A Kantar poll conducted between last Thursday and Sunday (so before the bombing) has topline figures of CON 42%(-5), LAB 34%(+5), LDEM 9%(+1), UKIP 4%(-2). TNS has a turnout model based partially on age, so has tended to show larger Tory leads... but this poll has it dropping ten points and falling into single figures. Tabs are here.
YouGov's weekly poll for the Times meanwhile has topline figures of CON 43%(-1), LAB 38%(+3), LDEM 10%(+1), UKIP 4%(+1) - a Tory lead of just five points. Fieldwork for this poll was conducted on Wednesday night and Thursday daytime, so is the first conducted entirely after the Manchester bombing. Tabs are here.
The Tory lead is clearly continuing to fall away at a rapid rate. On the face of it one might be tempted to conclude that the actual impact of the bombing was to help the Labour party, but I think it more likely that it's to do with the disastrous Tory manifesto launch. I posted earlier about the negative impact of the Tory manifesto. In contrast the Tories still seem to have a good lead on security and terrorism - in today's YouGov survey people say they trust Theresa May far more than Jeremy Corbyn to make the right decisions on terrorism (55% trust May, only 33% trust Corbyn) and the Tories have a strong lead on the issue of Defence and Security. That suggests to me the cause of the narrowing is far more likely to be the manifesto, row and u-turn.
As ever, all the usual caveats about one poll apply. Before one gets too excited wait and see if other polls show such a tight race, and whether or not other polls show any more impact from the bombing. As things stand though the election suddenly seems a little less of a foregone conclusion than it appeared at the beginning of the race.
