Ted Cruz's strategy to go after Donald Trump this early in the election may now be backfiring, NBC News reported.
With just days remaining before the Iowa caucuses, Cruz's campaign is facing a potentially consequential shift in momentum — one that could lift Trump to a caucus night victory and give Marco Rubio a significant boost heading into New Hampshire.
An NBC/WSJ/Marist poll released on Thursday showed an 11-point shift in Cruz's support from three weeks ago, moving Donald Trump from a 4-point deficit to a 7-point edge over Cruz. Rubio now has 18 percent of the likely caucus-goers' support — and Cruz's campaign went up on Iowa airwaves this week with an ad attacking Rubio on immigration.
A new Gallup poll shows Cruz's favorability rating among Republicans dropped nine percentage points to 55 percent, and his unfavorable rating rose seven percentage points.
