Trump’s Approval in the State:
March 10th 46-50 (Gravis)
April 12th 47-45 (Mason-Dixon)
April 20th 50-44 (Remington)
This is something to note. A 10-point turnaround is definitely outside to MoE of both polls as well. As his approval continues to improve in the state it is clear that he is likely to campaign against McCaskill now.
It's hard to extrapolate a trend from 3 different pollsters with different methodologies.
Exactly. That's not how polling works.
Also, if his recent campaign 'successes' with Roy Moore, Rick Saccone, et al. are any indications, he can go ahead, by all means.
