Then the ACLU should have said so. What it said indicated precisely what the article's "leap of faith" implied: Liberal Hypocrisy in its most common everyday form.
You're wrong. According to the article, the ACLU "...said that punch-card voting machines would ''disproportionately disadvantage'' African-Americans, Latinos, and Asians...". Voter-punched machines are less accurate and less reliable than machine-punched machines. Lower income districts probably opt for cheaper machines. A case can be made for being "disproportionately disadvantaged" without saying that it implies minorities are less capable. Stick with what the ACLU actually says, vs. what the author of the article implies it means.
