TPM dug up a fantastically hilarious anti-JFK coloring book produced by the GOP during the 1960 election. The following page is nearly the exact same attack that was used against President Obama during the healthcare reform debate.

Of course the Republicans have no problem allowing profit-motivated health insurance companies to serve as actual death panels, all in the name of making shareholders and boards of directors happy.
