“Christie would be driving.”
Would he come in to Manhattan over the GW Bridge?
You're asking someone who lives in Texas, a whole other country. I have no clue. But SamAdams may know...
There’s also the Lincoln Tunnel and the Holland Tunnel, which are much more likely options when driving up from the Trenton area. I don’t ever go as far north as the GW bridge (at the very north end of Manhattan) unless I am headed into New England and not into Manhattan.
Ofc Trump could easily helicopter him in, but I don’t expect it will be Christie.
