I based this on the observation that the day GW Bush was sworn into office, homelessness became a national issue.
Homelessness barely registered while Clinton was in office but it suddenly became prominent in the final months of the Bush/Gore election.
I remember it distinctly because there was a dramatic increase in the number of news stories.
It clearly wasn't a coincidence. It was a coordinated attack.
Likewise, as soon as Obama became president, the homeless disappeared.
What was really remarkable was that even after the greatest number of home foreclosures since the depression, there were no mainstream news reports about the rise in the homeless population.
They cycle of reporting is obvious.
Trump will be blamed for the rise in homeless.
That aside, one wonders why are there so many "homeless"?
Truth told, one suspects that Mister Obama's eight years of alleged presidency is behind much of the homeless explosion.
One suspects that Obama's policies on high taxes, medical stupidity, oppressive business rules, and massive illegal (and legal) immigration have made full-time, US Citizen employees a toxic luxury.
Dems and their policies are quite good at creating these human tragedies; and one does not notice any remorse.
Other reasons for homelessness of course exist, including substance abuse, mental illness, ill health (sadly including Hep A), running from the law, and that some folks do not seem to desire anything beyond "free stuff".
