Only one Republican (Joseph Cao, LA) voted for Obamacare. Every other Republican in the House and Senate, RINO and non-RINO) voted AGAINST Obamacare. Had the Congress had more Republicans, RINO and non-RINO, at the time there would be no Obamacare today.
So don’t tell me about your “principles”
The GOP offered its version of Obamacare as an alternative to Hillarycare, back in the day. Both parties in the federal government are determined to expand the scope of federal influence.
You delude yourself. The reason every RINO voted against ObamaCare is because it didn't matter. Remember if you will how it ever got to the Senate floor for a vote, in the first place.
