While Canadians can't run for U.S. president or give money to campaigns, Canadians are certainly part of the U.S. political process. Jennifer Granholm was born in Canada and was Michigan's governor for two terms.
The prominent Canadians in the U.S. political system these days are Republican. Even though the conservative Stephen Harper runs Canada, the country is still more liberal than the United States. If liberals want to go to Canada, conservatives would want to be in the United States.
David Frum and Dan Senor worked under George W. Bush, and Senor is still active in the process, working for presumptive Republican presidential candidate Mitt Romney.
While Senor was born in upstate New York, he did grow up in Toronto.
Senor previously served as the chief U.S. spokesman in Iraq, a position where he didn't fare so well. You might also remember that Senor is married to former CNN journalist Campbell Brown.
The other Canadian making political headlines is Ted Cruz, Tea Party politician and now the Republican candidate for the U.S. Senate seat being vacated by Kay Bailey Hutchison.
Cruz's ancestry on his father's side is Cuban and his mother is American. They lived in Alberta in the 1960s, working in the oil business. Cruz's family moved back to Houston when Cruz was four. His memory of Canada: "it was cold."
Cruz can't become president, but he'll likely get elected to the Senate in November. Senor can be president, but he may end up working for another president.
