Will the Escape loose out to the Tahoe hybrid among the candidates?

This past week Ford has been running ads touting the fact that their Escape Hybrids have been particularly popular among pandering presidential candidates in this extended campaign season. A big part of the allure of the Escape is surely due to the fact that it has been the only American branded full hybrid vehicle available. Odds are however, that the likes of Hillary Clinton and Barak Obama would much rather be chauffeured around in something with more stretch out room. Now that the Chevy Tahoe and GMC Yukon Hybrids are about to be released, how long will it be until most of those candidates make the switch?
