He supported frickin' John Kerry, one of the dullest and worst secretaries of state in recent memory (worse than HRC, IMHO). If he wants to join the Democrats, let him go ahead. But believe me, if he does not support Tillerson, he will be seen by all for what he is.
Tillerson is vastly unqualified to be SOS. His ties to Russia, his refusal to answer simple questions and his inability to convince me that he will look out for American interests is deeply problematic.
Rubio, a real conservative, will have to make his own decision on Tillerson. I think he will vote against Tillerson personally because his entire supporter base (me included) are hawks who dislike Tillerson.
Eharding, it seems that you are under the assumption that the Reagan wing of the party will die and roll over for Trump on everything. You are gravely mistaken if this is what you believe. I voted for Trump, but my loyalty is to conservatism not the Republican Party. When Trump is wrong people like will make it well-known. When he is right I will sing his praises.
Oh, and BTW - Almost every GOP Senator voted for John Kerry's nomination, you disingenuous hack. Including Jeff Sessions, Rand Paul, Mike Lee.
Ted Cruz, Jim Inhofe, and John Cornyn were the ONLY GOP Senators to vote against Kerry's confirmation.
