This has been one very heated debate and I can surely see both sides.
Detroit's Ambassador bridge has been in disrepair for a while now, and is in desperate need of updating. Canada now wants to lend the cash-strapped state of Michigan a half-billion dollars to kick start the building of a new bridge just up-river from the Ambassador.
This has created a firestorm and rightly so. Lots of people are very concerned about whether jobs will go to Canadians or Michiganders, private influences and government takeovers.
Do yourself a favor and dig into the issue. We are afterall discussing one of the busiest border crossing points along the entire US/Canadian border.
