The analysis encompasses Twitter sentiment from Aug. 11, the date Romney announced Ryan as his VP, to the present. It weighed some 412,440 online conversations that have taken place about Romney’s choice.

The Twitter analysis echoes the first national poll released after Romney’s running mate announcement. In a USA Today/Gallup poll released Monday, 42 percent said they viewed Ryan’s candidacy as a “fair” or “poor” move by the Romney campaign, compared to 39 percent who said it was an “excellent” or “pretty good” choice.

According to PoliPulse, 19 percent think Ryan is a “polarizing figure.” Although in Romney’s introduction of Ryan, he emphasized his new running mate’s ability to work with the other side of the aisle without demonizing the opposition, opinions of Ryan so far do seem to fall strongly on one side or the other.

President Obama's campaign, quick to attack Ryan’s for “extreme” views, wants people to know that Ryan "is actually the worst." A post on the campaign's official Tumblr attacks him as unconcerned about marriage equality, women's rights and the middle class in a "Hello!
