Millions of Americans are being informed they're being dropped from their insurance plans because the plans don't meet minimum Obamacare standards, but President Obama so far has stood by his promise that "if you have insurance that you like, then you will be able to keep that insurance." Insurance plans that existed on the individual market before the passage of the Affordable Care Act were "grandfathered" in, the president and his supporters have argued, and consumers only lost coverage if insurers altered those policies after the law took effect. In that case, Mr. Obama said last week, insurers had to "replace them with quality, comprehensive coverage."
