You need to turn on your sarcasm detector. Lots of Republicans out there looking to have pet multi-million (or billion) dollar projects paid for by the taxpayers. Contrasing their ideals with Jefferson's was meant to be a slap at them.
Yeah, using Jefferson to argue against taxes for public education is a sure sign of a whackjob. Jefferson was a strong proponent of publicly funded education.
A university lab is a perfect example of what he would desire to be supported by taxes.
Other examples of what he believed to be proper uses of taxes:
"...opening roads, clearing rivers, forming safe ports, and other useful works...
in making roads, openingrivers, building ports, improving the arts, and finding employment for their idle poor " (Notes On Virginia)
But of course he'd have a conniption fit at the idea of the federal government funding such projects!
