Hillary and Barack fight over the brie and chablis voters in Philadelphia's Main Line suburbs.Chicago Tribune:

Mike Lilian, an anesthesiologist from nearby Bala Cynwyd, has voted for candidates of both parties in the past but likes Clinton this time around because she seems "wily."

His wife couldn't say exactly why she leans toward Obama, except to say "he's charismatic, dynamic" in a way she thinks might improve the country.

"He seems a little naive," her husband said. "He has so much less experience in foreign policy."

"But don't you think it's about judgment too?" she replied. "He was against the war from the beginning."

Kind of vague, as expected among this well-heeled group. As usual, suburban women are swing voters.

What will be the dominant issue du jour now and in the fall? Still the war probably, but maybe the war will recede and security concerns will rise. Mention of health care and the environment, and for this group education is always on the menu. Maybe the coming big Dem tax bite will get their attention.

UPDATE: One note--my liberal women friends told me, before the Illinois primary, that their husbands liked Mitt, if they would ever vote for a Republican. These were businessmen, though, not anesthesiologists. And this is interesting, Chuck Todd, NBC, "McCain's Path to Victory" (needs an opponent before he can choose a veep):

So how can he beat Obama?

He will have to do well in the Rust Belt and dominate the economic issue in a way he's never done before. McCain could fix some of his problems connecting on the economy by his choice of a running mate, and there may not be a better "conventional" pick than Mitt Romney.

UPDATE: WSJ, "Fight for Suburban Women":

At a town-hall meeting Wednesday, meanwhile, Sen. Obama appealed to suburban moderates and those wary of big government. "We know that government cannot solve all of our problems, and we don't expect it to. We don't want our tax dollars wasted on programs that don't work," he said.

Wow, what happy talk--it's the latest iteration of the Al Gore "reinventing government", supposedly governing smarter. When will these voters figure out Obama loves big government--and lots of taxes to fuel it? He is the most liberal member of the US Senate, and was most liberal in the Illinois legislature.

Obama is trotting out his poor, old grandmother now that she is useful to him in Pennsylvania, to go after Hillary's voters. And he's got Caroline Kennedy. Making inroads:

Sen. Obama can credit his gains in the suburbs to voters like Lorri Primavera, a 48-year-old jeweler from Wallingford.

"From the beginning, I felt like I was going to support Hillary, but I'm definitely leaning toward Obama now," she says. "I always felt that having a woman in office would shift the way things are being done, but I'm getting more of a feeling that it doesn't have to come from a woman."

Well, at least that's only to the good--maybe we can move beyond this brainless identity politics. He's got a young Obamacan mom here:

The Obama campaign has also argued that it can win in the fall by drawing in Republicans like Jessica Etezady, 31, of Gulph Mills, who attended an Obama forum here Wednesday with her 11-month-old daughter and says she will support Sen. Obama if he is the Democratic nominee. "I just have a gut feeling that he's the most likely to actually get something done in Washington," says the two-time Bush voter.

That's the challenge, isn't it. But I don't think the record of the Do-Nothing Dem Congress is in the best position to support Sens. Clinton or Obama. Latest Pennsylvania polling here. Nationally here. Congress rating here. (Worse than the president's, though of course individual congressmen always fare better than the generic.) Rasmussen national daily tracking, and interesting breakdown:

Gender and race issues have been a major factor in the Democratic competition. A new Rasmussen Reports national telephone survey found that 37% of voters nationwide believe that African-Americans experience more discrimination than women while 27% hold the opposite view.

I suppose this favors Obama. Also this in Pennsylvania--population shifting to liberal and urban. Philadelphia Inquirer. UPDATE: New poll, McCain erases Obama's lead.AP-Ipsos.
