First, some math.
The population of Texas (according to a quick Google search and as of 2011) is 25,674,681. Even if we give the petitioners the benefit of the doubt and assume they are all from Texas (which they are not), there are still 25,572,533 Texans who have NOT signed the petition. If you're more of a percentages kind of person, those who HAVE signed the petition constitute .4% of the population. Yes, less than 1/2 of 1%. That means that 99.6% of Texans have NOT signed the petition.
So although the Obama Administration has pledged to address any petitions that reach 25,000 signatures on the White House petition website, the petitioners by no means constitute a majority of Texans.
Secondly, some facts.
Rick Perry, he who fairly recently hinted that he might support Texas secession, doesn't support the Texas petition to secede. If even Rick Perry knows which side his government bread is buttered on, maybe the petitioners should rethink this whole secession thing.
Additionally, we should consider if secession is actually treason. Article 3 Section 3 of the United States Constitution states:
Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort.
So it appears that, since the petitions are advocating PEACEFUL withdrawal, these requests are not technically treasonous.
Moving on, according to the Texas State Library and Archives Commission (sounds pretty authoritative, right?)...well, let me just put the direct quote:
And did further declare in the same proclamation THAT IT IS THE MANIFEST DETERMINATION OF THE AMERICAN PEOPLE THAT NO STATE, OF ITS OWN WILL, HAS A RIGHT OR POWER TO GO OUT OF OR SEPARATE ITSELF FROM, OR BE SEPARATED FROM THE AMERICAN UNION; and that, therefore, each State ought to remain and constitute an integral part of the United States
When was this proclamation issued, you ask? Shortly after Texas's LAST attempt to secede. This is part of the Presidential Proclamation that declared peace between the U.S. Government and Texas in August 1866, after the conclusion of the Civil War. So in order to be readmitted to the Union, Texas (and the rest of the South) HAD TO AGREE TO THESE TERMS.
Finally, just a note to all those advocating secession. You may think you don't rely on the federal government, but you do. Social security? Medicare? Interstate highways? Education subsidies? Farm subsidies? FEMA? Do any of these sound familiar? If you're that hell-bent on seceding, you must consider the pros AND cons instead of just going off half-cocked (as we say here in Texas) because the election results hurt your feelings.
Consider the math. Consider the facts. Texas will never secede. EVER.
UPDATE (as of 9:20am Central on 11/19/12): In the interest of fairness, I'm updating the math. There are currently 114,990 signatures on the Texas petition, many of which are not Texas residents. However, the updated percentage of people who HAVE signed the petition is .45% - meaning, 99.55% of people still have NOT signed it.
