The best way to see how the parties are going with targets appears to be on the BBC:
Here shows the seats the Conservatives have targeted to get a majority AND how they are doing.
This shows the same for the Liberal Democrats
LibDems have won ONE target seat.
Labour so far swung 6.1% to Conservative, but also Lib Dems have swung 0.6% to Conservatives.
BUT, at 34% at this stage, it is a GOOD result for the Conservatives. 28% for Labour is not.
