Advice for GOPe (tell Rubio to drop out NOW)
Only if you believe the poll most favorable to Trump, and assume that every undecided voter breaks for Trump, then only can Rubio win Florida by one percentage point. But more likely, voters will break away from Rubio because of his pathetic underperformance and the chatter in the MSM that Rubio is doomed and is being urged by his donors to drop out.
On the other hand, polls also show that Rubio is stealing a lot of votes from Kasich in Ohio and Illinois. If Rubio drops out right now and endorses Kasich, he will at least assure that Kasich has a big convincing win in Ohio and denies the delegates to Trump, and also boosts Kasich in Illinois where he would take more delegates from Trump with a good showing. Kasich would pick up a lot of momentum and donors, and he could effectively challenge Trump in the remaining primaries, especially the West Coast primaries where Kasich would be strong.
