You can certainly argue that, but you forget Justin Amash. Elected to Congress as a Republican this cycle. He spoke out against the President and even called for his impeachment and was summarily hounded out of the party.

Had he remained in the GOP he certainly would have made the vote bipartisan.

I would also like to point out that every single time a GOP member talked against the President they were quickly rebutted or rebuked by either the President or one of his enforcers. Even Matt Gaetz fell victim to this when he spoke out about the raid on Sulemani.

Let’s face it, from all accounts the President is hated by the GOP in the House and Senate for the most part. If the votes were confidential there are many that would vote against him but they dare not voice their concerns publicly for fear of retribution.
