Social media hasn’t been around long enough for pundits to determine how accurately it reflects the mood of a nation, but Democrats grasping for positive news might take hope from a shift in the tone on Twitter.
Our analysis of some 1.6 million tweets since August, using sentiment analysis software from market research firm Crimson Hexagon, shows a more favorable trend for President Obama’s party in recent weeks.
When we first examined online sentiment back in the summer, we found considerably less enthusiasm among Twitter users for the Democrats than for the Republicans.
In mid-September, however, there was a shift, with the number of pro-Democratic tweets rising to meet the pro-GOP numbers and eventually surpassing them. This dynamic has held relatively stable for the last month as you can see from this graph:
This movement is a continuation of the trend we noticed in mid-September. Pro-Democratic numbers began to pick up then amid the rise in the profile of the conservative Tea Party movement within the Republican party.
