I disagree - I actually think it would help the GOP!
We'd become a more moderate party, having to do so in order to win national elections. Being more moderate would help us in states like California and elsewhere which means the GOP would become stronger.
The Dems, on the other hand, would pull in the lefty whackos in Canada and would be un-electable anywhere in the current U.S. This would end any relationship between moderates and the Dem party, and strengthen the GOP even more.
So the GOP becomes more moderate and wins more elections, the decent parts of Canada get responsible leadership, and the Democrat party ceases to exist - its a win, win, win situation!
I like Canada; I love America.
I'm just saying that it would be great to have Canada as part of the US; then the Democrats would have an even greater chance of winning the election
Plus also, I think most americans would like to have Canadians as US citizens, they are always so polite. it would help our world image no end
