From an interview in Business Insider with Republican pollster Jan van Lohuizen (via Jonathan V. Last):
4. Everyone's sort of surprised by the inability of Tim Pawlenty to get traction -- so far -- with GOP primary voters and caucus attenders? Why isn't he connecting?
JVL: He is utterly lacking in charisma. I usually avoid these, but I agreed to speak at a regional organizing meeting for the party in Minnesota just to see him speak: he was utterly boring and I decided not to pitch his campaign. At a cocktail reception for the event, attended by 125+ activists, he and his wife were standing by themselves – no one was interested in talking to him and he made no effort to work the crowd. The first presidential campaign, I worked for John Connally’s; at an event like this one 120 of 125 attendees would have been all over him and he would have found the remaining 5. And Connally got 1 delegate, but in fairness he was running against Ronald Reagan.
The general implication of van Lohuizen's remarks is that nobody will win the GOP nomination.
