Of course they were allowed to vote, because it's the STATE that decides who may and may not vote, NOT the federal government.
Do you have any idea at all what you're talking about, or are you just pulling this crap out of your butt? The "General Welfare Clause" only refers to those things that are specifically containg in Article 1 Section 8 of the Constitution, or specifically allowed for elsewhere in the Constitution.
Now, take your childish little "roll eyes", and shove them up your butt, because all you're doing by using it is amplifying your gross, blatant, and complete ignorace of the subject material. Your using them, given your utter ignorance of the subject material reminds me of stupid little girls who roll their eyes when they've just been informed of how silly they're being, and coming off to their mother that "uhh, you don't understand", when it is THEY (and in this case, that would be YOU) who doesn't understand ANYTHING. I feel that it's only prudent to remind you of the age old addage that "it is far better to remain silent and be thought a fool, that to open one's mouth and remove all doubt"....FOOL!
And again you demonstrate your complete ignorance of the meaning of words in the English language. The 16th Amdment merely grants congress the authority to collect taxes from whatever source it may be derived, it does NOT grant them authority to SPEND that money on whatever they will, because as I have already shown, doing so was NEVER to be construed to be the meaning of the "general welfare" clause.
Seriously now, if you're going to express an "opinion" about a subject, it would behoove you to ACTUALLY KNOW SOMETHING ABOUT IT!
