WASHINGTON, Dec 1 (Reuters) - Five more U.S. senators signed on to support a sweeping Republican tax bill on Friday, but two holdouts remained. If all Democrats vote against the bill, Republicans can afford to lose only two votes from their own party. Here are the Republican senators pivotal to the bill's fate.
The moderate senator from Maine has said she is not committed to voting for the bill.
She has qualms about its inclusion of a repeal of a federal fee imposed on people who do not comply with Obamacare's "individual mandate" to obtain health insurance. Collins is worried this would drive up insurance premium costs, canceling out gains from tax cuts that many constituents might get from the bill.
She said she made progress on Friday on another concern, reaching agreement to change the bill so state and local property taxes are deductible from federal income tax up to $10,000, which would mirror legislation already passed by the House of Representatives.
Collins said Republican leaders have promised to address her concerns about healthcare by taking up two provisions before the end of the year to help mitigate the impact of repealing the mandate fee. Those provisions would help insurers cover expensive patients and continue Obamacare subsidy payments for low-income people for two years.
Corker, a deficit hawk from Tennessee, stalled momentum on the tax bill on Thursday by demanding Republicans look for more ways to keep the bill from causing the deficit to balloon. It was unclear if his demands had been addressed.
The Joint Committee on Taxation provided a new estimate on Thursday that said the Republican bill was expected to expand the national debt by $1 trillion over 10 years, far short of assertions by Republicans that the tax cuts would pay for themselves.
The Montana Republican has signed on to support the bill after having voiced concerns about its treatment of "Main Street" businesses. He said he had won more tax relief for non-corporate pass-through businesses, which include partnerships, sole proprietorships and other non-corporate enterprises.
The senator from Wisconsin endorsed the bill after demanding more for pass-throughs. The bill now features a 23 percent tax deduction for such business owners, up from the original 17.4 percent, said statements from Daines and Johnson.
The Arizona conservative announced in a statement on Friday he would vote for the bill. He said he had succeeded in eliminating an $85 billion expensing "budget gimmick" and received a firm commitment from Senate leaders and the Trump administration to work on permanent protections for immigrants who were brought to the United States illegally as children.
Oklahoma's Lankford came aboard on Friday after having questioned whether tax revenues from economic growth would compensate for an expected increase in the national debt.
He announced on Friday he was voting for the bill. Moran had earlier been wary of its impact on the national debt.
The Arizona maverick and former presidential nominee announced on Thursday that he would back the tax bill.
The senator from Alaska will vote for the tax bill, she wrote on Twitter on Wednesday evening.
