Sen. Lamar Alexander (R-Tenn.) said on Sunday that if Democrats push health care through under the majority only process known as reconciliation, it will be a "political kamikaze mission."
Though the individual parts of the bill are popular, he conceded, Republicans believe that opposition to it is strong enough that the party can run on a platform of repeal.
"For the rest of the year we're going to be involved in a campaign to repeal it," Alexander said on ABC's "This Week," adding that campaign would begin "the day it passes."
Democrats, in fact, would not be jamming the entire package through using reconciliation. The Senate and House have already passed major health care reform bills. Reconciliation would be used to amend the Senate bill with small changes demanded by House Democrats.
