Loreen's indeed getting major love on Internet, andhas been doing so ever since she qualified. For example, she's quite handily winning number of FB likes on the MF site. Also, she's number one on the iTunes charts now (before Danny at no 2).
However, one should remember that Loreen also looked quite strong in these matters last year (though not nearly as strong as this year, of course). For example, she was 4th/5th on the iTunes chart, making it look like she'd crush SC opposition. Not so, she didn't even win round 1 there. Bottom line is that it's not easy to know how much her support translates to votes. Her typical fan isn't really the typical MF-viewer, and even less so the typical voter. She might have won over a large group teen girls this time around though, an obviously important group.
Among middle-aged women, however, she's likely trailing Danny. He put up a suprisingly weak performance in the semi, rumored to be due to bad audial feedback (he had been singing quite allright druing rehearsals). Of course, the 7kg suit and crazy dance routine doesn't help.
It does help for the wow-factor, though. Where Loreen is beautifully minimalistic, Danny puts on quite the show. That, combined with inclination to vote among fans, gives Danny the nod for me. That is, with the popular vote - juries are even more unpredictable. Last year, however, they did not seem to have a problem with either gimmicks, nor Danny himself. But what will they think of Loreen's well sung number?
For Danny, there's also the risk of vote-splitting with Daniel Lindgren (I don't see such a risk for Loreen). However, we saw no such pattern last year, where Danny and Saade were top 2 with both public and juries.
To sum it up, this feels like a toss-up atm. However, if Danny can put on the needed show, he's my tip to win the whole thing. Of course, further analysis is needed after we know the 2 last entries, as well as performance order.
