They need to attract tory voters with a sensible (moderate) message
I know this is the accepted wisdom in UK politics but I dont think it really plays out that way usually. Seems like voters respond more to boldness in parties.
Last time around it was Boris with a big confident "we're brexiting and f*ck the consequences" policy vs Corbyn with an umm err not sure second referendum policy.
Before that Corbyn was the anti-establishment choice and Labour gained seats for the first time in 20 years.
When Cameron got in it was big hard tough tory cuts vs slower gentler Labour cuts.
When Blair got Labour in the manifesto had devolution, house of lords reform, voting system reform, rail nationalisation all included. Big bold policies. Okay he bottled it on most of them but that was the 97 platform.
At the last 4 general elections the SNP have swept up Scotland with their massive, dramatic break up the union policy.
For sensible moderate messages I suppose check out the Lib Dems. Or Change UK. Miliband when he was Labour leader. Not done much have they really?
