【单选题】

Flying across the country the other day, I sat next to a retiredAir Force colonel, and we had a pleasant conversation about love of flying, travel and grandchildren and for him, of retirement itself. "Yeah," he said, "there’s only one thing that would make me give this up. "

"What’s that "
"If Hillary or Jan Fonda runs for president, I’m going to work full time to beat her. "
I told him I knew Hillary. She doesn’t even need a last name now.And she’s no Jane Fond
A、
"Well," I concluded before we began talking about planes and kids again, "I think you are going to get your chance. I think she’s going to run. "
I once wrote, with total sincerity, that I thought Hillary RodhamClinton had the political instincts of a stone. I also wrote that I thought she had marginalized her husband’s chances of being an important president.
He blew that by naming his wife to head the task force to work out a national plan, and she decided to work in secret with battalions of "experts" who came up with a plan four times as long as theEuropean constitution.
Then, after taking her lumps for that, she decided to run, as aDemocrat, for the US Senate from New York, a state she had always thought was a nice place to visit.
She is now far and away theDemocratic front-runner for president in 2008. Her national numbers are getting better, inch by inch, day by day. Now, a slight majority—52 percent in a couple of polls—say they are likely or very likely to vote for Hillary for president. True, 47 percent, including my friend the colonel, still say "Never. "But her national approval-disapproval rate is now about 55 to 39, compared with 46 to 48 for PresidentBush.
The odds are still against her. So are most of the odds-makers, beginning with Joe Klein of Time Magazine, chronicler of theClintons in fact and fiction. He believes a Hillary candidacy will polarize the country the way the reign of theClintons polarized us in the 1990s.
The word "polarize" in the last paragraph probably means ______.
A、personalize
B．popularize
C．unite into one group
D．divide into opposing sides
