Campaigns supporting Colorado Democratic legislators facing recalls over new gun restrictions have raised nearly $2 million.

New York City Mayor Michael Bloomberg and billionaire philanthropist Eli Broad have each contributed large sums to Taxpayers for Responsible Democracy, which is working to keep Senate President John Morse of Colorado Springs and Pueblo Sen. Angela Giron in office. Bloomberg, who has advocated for stricter gun laws, contributed $350,000 and Broad $250,000.

Pueblo United for Angela has raised $586,000 and A Whole Lot of People for John Morse $606,000, according to state campaign filings Tuesday. Taxpayers for Responsible Democracy has raised $708,000.

The National Rifle Association has spent about $108,600 to oppose the lawmakers. It’s among the largest contributors to opponents of Giron and Morse.

The election is Sept. 10.
