LETHBRIDGE, Alta. -- Alberta Premier Rachel Notley and United Conservative leader Jason Kenney both spoke to crowds in Lethbridge last night with a common message -- voters will have a stark choice on election day.

Notley urged cheering supporters to re-elect an NDP government on April 16, warning that only her team will fight to protect public health care and ensure that all people are treated fairly.

She also attacked Kenney, saying she knows there are conservative supporters who are unhappy with how he won the UPC leadership.

Notley says she will work her tail off to win their support and that Kenney is not fit to be premier.

In a different part of the city Kenney blamed Alberta's economic downturn on NDP policies that he says have driven away investment and killed jobs.

He says it is up to people to vote for change and UPC policies that under his leadership will get the province back on track.

This morning, Alberta Party Leader Stephen Mandel is to announce a plan to double the number of educational assistants in K to 12 classrooms.

Later today, the three party leaders are to shift their campaigns to Calgary for speeches and rallies.
