Sen.

The vote-counting process, known as "whipping," will give GOP leadership a tentative count of which senators support the legislation spearheaded by GOP Sens. Lindsey GrahamLindsey Olin GrahamSenate GOP: Legislation to protect Mueller not needed Cornyn: Hearing on McCabe firing would be 'appropriate' McCain: Mueller must be allowed to finish investigation 'unimpeded' MORE (S.C.) and Bill CassidyWilliam (Bill) Morgan CassidyHere is a health care proposal that could actually work Senators target 'gag clauses' that hide potential savings on prescriptions Kimmel: Political pleas on health care have cost me commercially MORE (La.). 
"What I told Senator Graham is we would work to try to get a sense of where people were ... so my hope is we'll get that preliminary information back in the next few days," Cornyn said, when asked about the vote counting. 
He added the process could also identify members who are undecided or have follow up questions. 
Instead, the bill would convert the funding into block grants to states. 
But the legislation faces an uphill effort to getting through the Senate by the end of the month—when the special budget rules that allow the healthcare bill to pass by a simple majority will expire. 
Republicans are currently waiting to get a score back from the Congressional Budget Office (CBO), which would say how much the bill would cost and how many individuals would gain or lose insurance coverage. 
They would also need to win over at least 50 Republican senators, which could be an uphill battle after they failed to clear a "skinny" ObamaCare repeal bill in July and with many of their colleagues eager to move on. 
The bill was also discussed during the closed-door GOP caucus lunch on Thursday, with Graham and Cassidy making a presentation. 
Graham said after the fact that he thought they had gained support and was happy with Majority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellSenate tees up Yemen vote for Tuesday Senate confirms Trump's border chief House leaves out ObamaCare fix from must-pass funding bill MORE's (R-Ky.) response in the lunch. 
"He encouraged everybody to jump on board....I'm very pleased with the leader's response," Graham said.  
The GOP senator added that "I can tell you this if we had a vote right now we would get 47, 48 votes."
