Why aren't Democrats raving delusionally about Lincoln unlike Santorum?

I like her for endorsing Hillary (but I guess seeing as how she's from Arkansas, that was kind of expected) but here's a question: When, exactly, did her approval ratings start to dramatically decrease - was it before or after (or during) the primaries? I volunteered Monday night to do phone banks for a friend of mine who's working on her campaign and I called around 100 people in Springdale, Arkansas, most of whom were Democrats, and the majority of them were undecided about whether they were going to support Lincoln but none of them mentioned that they were going to support Halter (matter of fact, his name didn't come up once in the course of my phone calls). Maybe the news that he was going to primary Lincoln hadn't reached them yet, who knows, but still just shows a lot of uncertainty out there with Lincoln.
