Maybe if George McGovern had won the White House in 1972, and then kept fighting the Vietnam War.
Or if Bill Clinton had urged health care and the Democrats had passed it 50 times in the prior 8 years.
Or if Reagan had won and shrunk the military budget.
Or if Carter had not passed amnesty.
In, other words, it is hard to imagine a more central promise made by a party then given the tools to fulfill it, that got “moved on” from.
Thats not how you win coming elections. Midterms or Presidential.
