Sen. Ted Cruz’s (R-TX) presidential campaign “may not get many endorsements from Senate colleagues. Not coincidentally, the Texas senator is racking up support from primary challengers who tried but failed to unseat some of those senators last year. Tennessee’s Joe Carr, Mississippi’s Chris McDaniel, and South Carolina’s Lee Bright, three conservatives who opposed longtime GOP senators in 2014 primaries, have all backed Cruz for president,” National Journal reports.

“It’s a small part of Cruz’s effort to do next year what those candidates did last year: serve as a vessel for conservative voters’ frustration with the political establishment.”
