I applaud your efforts, but I believe the Constitution precludes you from doing that (although I beleive there may be precedent)
I meant "believe", honest!
Oregon may not be able to split into two states, but didn't the Compromise of 1850 (where Texas joined the Union and gave up its rights to Colorado and New Mexico in return for payment/forgiveness of war debts) give Texas the right, at any time, to split into two states, each with its own Senators and Representatives?
That's why I'll always think of Colorado as Baja Texas.
