The positive for Grimes is that McConnell is still polling in the mid 40's and has an approval rating of only 10% in this poll's undecideds. Therefore, the undecideds will likely break towards Grimes by a considerable margin. That being said, it seems unlikely that that will be enough for her to close the gap. The race none the less remains a leaning GOP toss-up. The trend indicates that McConnell will win by a couple percentage points.
Today is the Minnesota primary election. We will have the results tonight. The only effect on my predictions will be the Gubernatorial. Since all the candidates are polling similarly against the incumbent, my number will not change by much.
The last remaining consequential primaries are Alaska next week and Arizona the week after that.
