Major campaign underway to nullify Electoral College

[Joe Republic]

Forgive me if I've missed this, but is there a time limit for this compact to take effect?

Illinois used to distribute seats in the Illinois Senate seat equally to every county, although that was eventually declared unconstitutional.

You mean to say that they found a problem with two state senators representing as many citizens as every other senator combined?

Well sir, I for one am shocked.

In Tennessee, a Republican has introduced the NPVIC into the Senate and a Republican has introduced the NPVIC into the House:

3 Republicans have introduced it in Arizona:

Why are Republican legislators in Republican states taking up this issue?

[Joe Republic]

Hypothetical question, that I probably already know the answer to...

Let's say enough states enact the law to enable it to take effect, but only just enough, say 272 electoral votes.  A presidential election takes place using this new system.  Then the census takes place, followed by reapportionment, and suddenly the collective number of electoral votes drops to 266 or something.  Do we then go back to the current state of things, until more states opt in?
