The Democrats push for open borders is not accidental, or just a push to the left. The push for open borders is deliberate and pre-calculated in the party think tanks. Since the sixties, the Democratic Party has kept African Americans on the plantation, with legislation designed to keep poor blacks appeased through massive hand out programs, while fighting against any tax reductions. This was done because the Democrats knew if taxes were lower, that would create opportunity. Opportunity is the antithesis of the Democratic philosophy.
Democrats were successful for decades to hide their true intentions, because human nature of free and easy hand-outs for the most part kept the poorer African American population at bay. Now, as more light is being shed that the whole purpose of these easy access welfare programs was to keep the blacks down, and keep their voting bloc. The African American people are waking up to realize that through hard work, like every other American, dignity, and responsibility are the path to a better future. Not generational dependency.
My point is that as more of the African American population come to realize they have been duped by Democrats, simply for their votes, the Democrats need another sucker to dupe. This just conveniently happens to be the massive influx of poorly educated illegal immigrants that are pouring into our country.
Just as opportunity for better education for blacks in the sixties provided the ignorant populous needed for those additional votes then, there now is a new readily available source of ignorant voters ready and willing to swallow the guff of freebies to provide a whole new bunch of suckers to vote Democrat for the exchange of the welfare bribe readily available.
