Clinton was elected on explicit Third Way positions nearly 30 years ago. If you think something changed in the past 10-15, you're falling for GOP propaganda. What you're noticing is the democrats finding a new base a decade after losing their working class supporters, through a combination of Third Way politics, the Republican Southern Strategy. The GOP saw this coming and stoked / capitulated to increasing racist elements of the party during Obama's presidency. This is the only major change in the past decade.
(Well, the democrats aren't really that smart - it's not so much they're finding a new base as they're left with the ones the new GOP ideology intentionally excludes. As a party, they are doing a terrible job mobilizing this!)
