They keep saying this but they never mention the huge crossover party registration to the GOP, the huge increase in first time voters, and the huge voter turnouts that have Trump 2 million votes ahead of the other GOP candidates, even with 17 running
Nor do they mention the vast inroads the hopeless cause Bernie Sanders is making on candidate presumptive Clinton and the low overall democrat turnout vs the GOP
The crossover votes will be voting Democrat in the fall. Right now they are just attempting to put in place the worst nominee to oppose Hillary.
The crossovers cannot be counted on.
They will vote for Hillary or Bernie.
We cannot win with Trump.
