"This is sort of a repetition of 'If you like what you have, you can keep it' false promise, because many seniors are finding that the $300 billion that has been cut out of Medicare has been then used to try to fund ObamaCare," Cornyn said Sunday afternoon, two days before his primary.

"Medicare Advantage has been a tremendous success, it's growing because seniors like the innovation, the choice and the range of services that they have have available to them, but this of course threatens this private-sector alternative and will force people into a single-payer option."

Republicans have been hammering Democrats on a planned 2-percent reduction in payments to Medicare Advantage programs, seeking to further erode support for ObamaCare.

Cornyn has been a vocal opponent of the law from the start, and has ramped up his criticism of ObamaCare leading into his primary against Rep.
