After Cruz's Wisconsin result it appears the "vote stealing" in Colorado has been a train wreck for him.
Cruz has dropped a huge 6 points from 38% to 32% whilst Trump has risen from 39% to 44% giving him an 8 point nationwide lead. The new CBS poll has his lead even larger at 13 points.
The trend line is obvious;
As is the most recent nationwide aggregate poll of all polls
Trump also has the highest head to head polling against Hillary Clinton
In the new Fox poll more disaster for Cruz
And huge lead in Pennsylvania
