It's impossible to read voters' minds. But the combination of low faith in Romney's ability to defeat Obama and his relatively low favorability ratings suggests he has yet to persuade most Americans he is cut from presidential timber.
There's ample time to remedy that. And, of course, the weak economy might sink Obama without Romney having to raise his popularity.
Romney's camp undoubtedly wants to use the convention's remaining hours — especially his Thursday night acceptance speech — to burnish his likability and plausibility. There's work to do.
Most registered voters viewed Romney unfavorably when the convention opened, a recent Washington Post poll found. He is the first party nominee with higher unfavorable than favorable ratings at this stage since Walter Mondale, the 1984 Democratic choice.
In the same poll, 61 percent said Obama was more "friendly" and "likable" than Romney; 27 percent saw it the other way around.
Several Republican strategists said they are not terribly worried about Americans' predictions of the Nov. 6 winner.
"That data fails to measure the intensity that voters bring to the table," which favors Republicans, said veteran consultant Terry Holt. "Romney still has to close the sale, but he's still got plenty of time."
Holt added: "I'd be more concerned if it were two or three days before the election."
Millions of Americans will tune in Thursday night for Romney's acceptance speech. Aside from the three October debates with Obama, it will probably mark his best chance to start closing the plausibility gap.
