Being in Texas, traveling to Nebraska, and knowing family in the oil industry in Texas, I've seen and heard both sides of this debate.
The four big reasons supporters have backed Keystone/TransCanada's pipeline are that it will provide domestic oil, an increase in jobs, and money into the economy, all while being safe to the existing environment.
Problem is, none of those things are true.
The linked Cornell University report goes right to the source for jobs, safety, and output data--KXL and TransCanada's own documentation submitted to the individual states in question stating the number of jobs they'll create and for how long.
First off, 13,000 jobs is incorrect. We're looking at approx. 5k
temporary jobs that will be created, with the majority of those temporary jobs expiring in two years time. Cornell University used KXL's own state-by-state submissions to come up with the numbers of people that will be employed. Of note, TransCanada's own estimates (Based on data provided by TransCanada to the State Department) only between 506 and 1,387 workers would be hired locally, with the majority of these new hires being in Texas where the oil will be refined for export.
And if you want to use the 'residual job' number for an argument, please understand that KXL/TransCanada have standing contracts with Indian and Chinese steel pipeline providers. Additionally, TransCanada has already purchased and imported a significant portion of the pipeline. So other than a few hands to put the pipe together, there will be little in the way of residual jobs, and what jobs are created will last only for a couple of years at best. And if you think TransCanada is going to break an international business contract to get steel from the US, you've been living in fairy tale land for too long.
That comes to point number two--the oil will *not* be for domestic (United States) use. It's already been stated time and again this oil is intended for export to developing nations--specifically China, India, and Brazil. While another poster here was correct in ascertaining this would ultimately drive down overall oil prices, it does nothing to shore up domestic energy security or short-term oil prices. The oil is too dirty for domestic consumption, but is fine for emerging countries with low to no air quality standards.
This comes to the next point--pipeline safety. The linked Cornell University report highlights 14 known reports of spills from KXL in 2010 (2011 isn't available yet) from a similar pipeline carrying a similar type of 'dirty' tar sand oil. And these are only the reports we know about that came from within KXL.
Now, I could care less if you're a hippy tree hugger or that you backyard compost, wipe your butt with palm leaves, or whatever--but common sense dictates that you don't let pollutants come close to where you eat or drink, and the Nebraska aquifer in question is both, as it provides drinking water and water for crop irrigation. Plus, Nebraska isn't just impacted by this--Kansas, Oklahoma, Arkansas, Missouri, and Texas are all impacted if something happens to that aquifer.
Finally, the amount of money that Keystone will spend in the US on this deal isn't in the tens of billions that people are throwing around. The Cornell University report found that the real money that will be spent in the US will be closer to $4.5 to 5 billion US. The tens of billions we keep hearing are the amount being spent on the *overall* project--the project that has 30-40% of its infrastructure in Canada. Additionally, much of this money has already been allocated--per KXL and TransCanada themselves, they've already spent over 70% of it. So the real leftover money the US can expect from this deal is significantly smaller than what we're hearing.
Oh, and if you've been DATY for too long and haven't paid attention to the news, the oil is still flowing to Texas, despite the lack of a pipeline. It's going by rail, which is what is so sad and funny about this discussion--the whole time, KXL has been playing people saying that the processing will go elsewhere, but it can't--TransCanada doesn't have anywhere else remotely close that can process the oil, save for existing contractors in Texas. So instead they're sending it by railcar, which makes Warren Buffet all the smarter for having picked them up months ago.
The sooner that proponents of the pipeline can realize they're being played like a fiddle, the sooner they can perhaps go back to enjoying the fine quality women this board helps us get in contact with. And frankly, that will be a lot more enjoyable and more worth the effort than parroting lobbyists.

Also, just for clarification, Nebraska is technically a purple state--they dole their delegates out proportionally per the popular vote, so Obama did get a delegate (Omaha, Lincoln) from the state, though the other two went to McCain.
