SHELDON G. Adelson, son of a taxi driver and the operator of a knitting store, was raised as a Democrat. In recent years, he has become an influential contributor to the Republican Party.
He explained why in a column headlined, "I didn't leave the Democrats. They left me," in the Nov. 4 Wall Street Journal.
"My critics nowadays like to claim it's because I got wealthy or because I didn't want to pay taxes or because of some other conservative caricature," he wrote.
"No, the truth is the Democratic Party has changed in ways that no longer fit with someone of my upbringing."
In part, it was the Democratic Party's shocking hostility to God and Israel and Jerusalem, the capital of the only liberal democracy in the Middle East.
"When members of the Democratic Party booed the inclusion of God and Jerusalem in their party platform this year, I thought of my parents," Adelson wrote.
"They would have been astounded."
But this self-made billionaire also laments Democrats' economic policies.
"When you look at states where Democrats have
enjoyed years of one-party dominance - California, Illinois, New York - you find that their liberal policies simply don't deliver on their promises of social justice."
