The campaigning continued on Saturday as Ontario NDP leader Andrea Horwath stopped in Windsor for a second time.

Horwath is promising a freeze of tuition fees, a 15% cut of hydro rates, and a job creation and investment tax credit.

"Are you ready for a government that treats you with respect?" says Horwath.

"We are going to respect your tax dollars and invest them into your priorities," she adds.

Horwath's visit comes less than a day after the Canadian Press acquired a letter from 34 longtime NDP supporters saying they are "seriously considering" not voting for the party June 12th.

The letter states current supporters are "deeply distressed" by what they see as the party's shift to the right.

But in Windsor, supporters disagree.

"People are entitled to their own opinion but I think they are absolutely dead wrong. We could not possibly support that budget," says Windsor-West MPP Brian Masse.

"We have a solid team, and there's no real issue in the sense we have a solid platform," he adds.

Howarth did not acknowledge the letter, just saying: "The good thing about our party is that it is very democratic. People have a right to voice their opinions."

She says her party's platform reflects the concerns of voters and they are the ones who will be making the call come June 12th.

Some political analysts say the NDP needs to work quickly to try and convince traditional New Democrats that Horwath is not abandoning the party's principles to get into power.

Horwath's decision to trigger an election also did not sit well with some union leaders, who considered the Liberal budget very labour and NDP friendly.
