Those are the conclusions from the second instalment of PRWeek's General Election sentiment tracker, developed by Meltwater Buzz.
The latest figures span the week from 19 April onwards, and demonstrate the Lib Dems continuing to surge following its strong performance during the campaign's first fortnight.
Buoyed by the #nickcleggsfault Twitter campaign and a strong performance in the second Leader's Debate, the Lib Dems recorded a huge spike in sentiment, registering a 34 per cent upwards swing on the 22 April.
However, by last weekend, the Lib Dems had suffered an equally large drop, plunging by 36 per cent to its current online sentiment of -9 per cent as of yesterday.
The results suggest that the Lib Dems online bubble may have burst, with Tories moving steadily ahead to an online sentiment score of +5 per cent. Labour, yet to record any positive sentiment throughout the campaign, are trailing in third place at -10 per cent.
