Springboarding off a post by Brendan Nyhan, Yglesias explains how Wilson's illegal immigrant lie could be twisted to be put in the highly misleading category:
[T]hough the bills would prevent undocumented immigrants from receiving any taxpayer assistance in purchasing health insurance, the proposals on the table don’t do anything special to prevent an undocumented immigrant from buying health insurance with his own money. To characterize this as “insur[ing] illegal immigrants” strikes me as about on a par with claiming that Obama’s health care plans give ibuprofen to illegal immigrants. After all, nothing in the bill stops illegal immigrants from buying ibuprofen in a store! And the very same FDA regulations that assure citizens and legal residents and tourists of the safety of ibuprofen will also benefit illegal immigrants.
