I agree with you. Ted Cruz should have registered his NO vote on the Loretta Lynch confirmation. When you have somebody like Loretta Lynch, who is just fine with unlimited executive power, up for a vote, you should be there to cast your NO vote, even if you know you cannot win. You will be doing right by your constituents.
And doing his job, as opposed to running around campaigning. There’s a time and a place for everything. Either that, or he should resign his seat.
