With advance polling starting Friday and only 10 days left until Election Day, the latest nightly tracking by Nanos Research for CTV News and the Globe and Mail shows the Liberals continue to trend marginally higher than the Conservatives.

Liberal Leader Justin Trudeau says he learned long ago not to pay too much attention to the criticism levelled against him or his family name.

The Conservatives have about twice as many business people running as the NDP, Liberal candidates are much more likely to be lawyers, and nearly all of the union officials and blue collar workers running for seats in the Oct. 19 election are New Democrats.

There are more than 500 staff in Stephen Harper's sprawling Prime Minister's Office, about 100 more than when he took office in 2006.
