Can Texas Secede?

TIME Magazine suggests that it can't - The War of Northern Aggression/American Civil War/War of the Rebellion,  in the mid 1800's may have killed that opportunity, but TIME also says, "...but the state does have the right to split into five states, offering the prospect of 10 US Senators, math that would send cold shivers down the Democratic back." 

I checked SNOPES.COM to see if they agreed. CLICK to read their opinion. They say, YES, Texas could be legally subdivided into five states. I further checked WikiAnswers.com and they agree with snopes.com -- CLICK HERE.
