What the Democrats count on...is that urban areas will deliver the massive votes of the future. So, this would virtually guarantee only Democratic contenders from 2020 on. Then, you could forget about North Dakota, Idaho, and twenty odd states....just focus big money on urban areas.
The logic has one flaw. As these new Latino voters get integrated into the system....they will eventually start to flip around fifty percent of their vote toward the Republicans. It might take another decade, or even two decades...but half of all Latino voters will eventually vote Republican. So, this crafted vehicle is not that stable or effective in the long-run....if you ask me.
Given that there is plenty of damage in just the last 5 years, 10-20 years of ‘Rat control until there is 50% Latino vote for Republicans is asking for quite a bit of damage.
Not all that different from the present system. Only swing states really matter in the EC vote at the moment, so CA, TX, and MA are ignored while FL and OH are politicked to death.
