From 2009
" The Senate Repubican Policy Committee estimates that 5 million of the 47 million uninsured are illegal immigrants. Richard Wolf of USA today has an even higher estimate, claiming that over 7 million of the uninsured are illegal aliens"
Obviously there are disagreements on the figures. Dont believe anyone who AUTHORITATIVELY states that 18 million of the 47 (not 45) uninsured are illegal immigrants which would make that almost 40% of the uninsured.
Likely? Silly? More likely.
