Trump beat her in 1 out of 4 of the polls RCP has. Cruz beat her in 3 out of the 4. No shifting or news here especially with results within the margin of error.
Clinton is becoming a weaker candidate by the day, that’s for sure. This is one of the few polls ever done with every GOP guy beating her. But she’s so weak, Sanders will probably be the nominee now.
Since Cruz isn’t the nominee, though, irrelevant. The only thing that’s important is that TRUMP beats her. Good enough for me.
