So, let's look at how people in each of these cities have voted in the last three elections.
First, Fredericton. The provincial capital has a metropolitan population of about 86,000 people, and its limits encompass part or all of five seats. The city elected mostly Liberals in the last election, so it will be necessary for the Progressive Conservatives to snatch a seat or two away from them in order to form government.
The Progressive Conservatives were at a high of 48% in 1999, but sank to 38% in 2003. They only gained a little in 2006 so they have a 10-point gap to overcome if they want to take the lead here.
The New Democrats have a bit of a base here in the city, as they took 20% of the vote in 2003. But they lost more than of that, and most of it to the Liberals, in 2006.
Next, Moncton. The biggest city in New Brunswick with a metropolitan population of about 127,000, Moncton is home to part or all of seven seats. Both Liberals and Progressive Conservatives were elected here in 2006, so it will be a battle of offense and defense for both parties.
The Liberals saw big gains in 2003, going from 30% to 43%. But they were stagnant in 2006 with a gain of only one point to 44%. With the NDP vote so low, they need to take support from the Tories in order to make some new gains in the city.
The NDP does not have a good base here, earning 10% in 1999 but going from there to 8% in 2003 and 4% in 2006. They shouldn't challenge here.
Finally, Saint John. Located on the Bay of Fundy, Saint John is home to about 123,000 people and all or part of seven seats. The city elected a mix of Liberals and Progressive Conservatives in 2006, and was the home of Elizabeth Weir, the long-time only NDP MLA. So it will be a battleground for all three major parties.
The Progressive Conservatives lost a lot of support between 1999 and 2003, going from 49% to 36%. They only tread water in 2006 with 38%, so they need to make some real headway in the city if they want to elect more MLAs.
Because of Weir's history, Saint John is the NDP's best bet for an urban seat. But they need to rebuild a lot of lost support. The party was at 21% in 1999 and 23% in 2003, but fell to only 6% in 2006 in the NDP's first Weir-less election in over a decade. Can the NDP regain some of that lost support and make a surprise upset win?
Aside from a few individual riding battles, these three cities will be where the political blood is spilled. But the Liberals hold the lead in other urban areas, like Miramichi (57% in 2006 to the PC's 37%), Dieppe (50% to the PC's 47%), Campbellton (56% to the PC's 44%), and Bathurst (49% to the PC's 46%). The Tories hold the edge only in Edmundston (70% to the Liberals' 27%), meaning they either need to make some headway in New Brunswick's smaller cities or rely on a good portion of the rural vote.
