, who first reported the Paul endorsement early this morning, makes a notable point
The endorsement may or may not move votes in the primary, but it adds to the narrative that Cruz is trying to build, which is that he would fit best with a small group of recently elected senators, such as Lee and Paul and, yes, Marco Rubio, trying to take tea-party values to Washington, shaking up the GOP establishment on Capitol Hill.
There are some similarities between the first-term senator and the conservative upstart in Texas. Like Rubio, Cruz is Cuban and has a compelling family and life story. But Rubio has indicated that he is not endorsing in his own state's Senate primary, nor is he backing a presidential candidate in the GOP primary, and has given no indication he wants to wade into the Texas Senate race.
