The progressive group Tax March on Wednesday announced the launch of a seven-figure campaign to push for increasing taxes on wealthy individuals and corporations, as a number of prominent Democratic lawmakers have been offering proposals aimed at making the rich pay more in taxes.

The group said it will spend more than $1 million on advertising to educate the public about taxing the rich more, and will also engage in efforts such as rallies, district office visits and town halls.

Tax March plans to focus its efforts in states that are important in the 2020 Democratic primary and the general election, such as Iowa, New Hampshire, Nevada and Colorado.

“The goal of the ‘Tax the Rich’ movement is to raise the visibility of this issue until it becomes impossible to consider yourself to be a progressive leader if you do not support taxing the rich,” Tax March Executive Director Maura Quint said in a news release.
