WASHINGTON -- Rep. Adam Smith said Monday he likely will support the health-care bill that the House may vote on as early as this week -- despite being the subject of an advertising blitz by the U. S. Chamber of Commerce to kill the legislation.

Smith, D-Tacoma, is the only member of Washington's congressional delegation to be singled out for the Chamber's anti-reform ads, on which the business group plans to spend as much as $10 million to air on national cable networks and local stations and which targets wavering lawmakers in 17 states.

Smith voted for the House health-reform bill in November despite "strong misgivings" that it was too costly, too complicated and didn't go far enough to slow Medicare spending and curb inefficiencies. The bill passed by a narrow 220-215 vote.

Now Smith and other House members are gearing up for a revote, this time on the version that the Senate passed in December, as a way to circumvent Republican opposition to reform.

Perhaps sensing an opening in Smith's less-than-wholehearted initial yes vote, the Chamber has been running ads in the Puget Sound area urging voters to tell Smith to vote no.

"They think I can be persuaded," Smith said.

But it may be for naught. Smith said he liked many things about the Senate bill, including the fact that it costs less and imposes lower fees on employers that don't provide coverage.

"I would be very likely to vote in favor of the Senate bill," Smith said.

Smith said his ultimate decision, however, will depend on the changes and amendments now being worked into the House bill, and whether he finds them acceptable.

Smith's website is running a poll on whether the House should pass the Senate version of the health bill. Smith said the tally may be running more agains the bill than for, though he said the Chamber ads "could be skewing the short-term results."

(I incorrectly reported earlier that the tally was running 3,600 for and 3,600 against. But those numbers include not only the online poll, but calls, letters and other forms of feedback received by Smith's office.)
