Isn't this just a name-recognition thing?
Yes.
In that case, it's terribly, terribly sad Gingrich is so low.
Not really. I mean, Speaker of the House during some of the 90's isn't even remotely comparable to someone who was the #2 Republican guy during an election that just finished two weeks ago.
It all lines up very strongly with name recognition, not actual approval of a guy's candidacy.
Every American born before 1990 should know who Newt Gingrich is.
I'm not saying this like "bawww everybody else is stupid," I'm saying the vast majority of the Republican electorate should be fairly familiar with Newt Gingrich. While he hasn't been in the headlines the in the last year like all the others, I feel he should have comparable name recognition.
Some people don't even know who the Vice President is, much less who the speaker of the house in the 1990s was. You give people too much credit. The general population are idiots.
