Roll Call is reporting that Senate Republicans are practicing a strategy to peel off moderate Democrats to defeat the health care bill:

Convinced for the first time that they can bring down Senate Majority Leader Harry Reid’s (D-Nev.) health care reform package, Republicans are trying to get votes on more amendments as part of a strategy to divide the Democratic Conference and turn a few wayward moderates against the bill.

A group of moderate Democrats have repeatedly joined the Republicans in supporting losing amendments aimed at removing Medicare cuts and tax increases from Reid’s bill, and the GOP believes there are only so many of these losses centrist Members of the majority can stomach before they walk away from the health care package in its entirety.

“We’re being successful at helping the American people understand what this bill costs, what it will do to them, and as a result of that, the American people are turning against the bill and the Democratic Senators are hearing from them,” Senate Republican Conference Chairman Lamar Alexander (Tenn.) said Monday. “They’ve had a steady stream of bad news. I mean, their theme song ought to be, ‘Raindrops Keep Falling on My Head.'”

The next tough vote Republicans intend to force is an amendment by Sen. Mike Crapo (R-Idaho) exempting families earning less than $250,000 a year and individuals earning less than $200,000 from having their taxes raised to pay for health care reform.
