I am doing a research paper on the 14th Amendment, Section 2, Sentence 1. ["Representatives shall be apportioned among the several states according to their respective numbers, counting the whole number of persons in each state, excluding Indians not taxed."]

I was wondering if you knew what ever happened to Rep. Candice Miller's proposed constitutional amendment to change the Census count to include only U.S. citizens.

Can you direct me to some articles that explain what happened to it?

James Fulford writes: There was a lot of opposition to it from the usual suspects. You can check the book  Vote thieves: illegal immigration, redistricting, and presidential elections, by Orlando G. Rodriguez for  details of the opposition to this plan, but in general what happens to a proposed constitutional amendment is …nothing happens, for years and years, and years, unless there’s an enthusiastic and well-funded mass movement in favor of it. The last serious attempt change the constitution was the Equal Rights Amendment, and that failed, largely because Phyllis Schlafly stood like a stone wall in its way.
