High turnouts were reported Thursday in Colorado Springs as voters made their way to election centers during the first day of early voting in the recall election of State Senate President John Morse.

The Colorado vote is being closely watched around the country as a litmus test of how the public responds to stricter gun measures in swing states.

Morse, a Democrat, and Sen. Angela Giron, a Pueblo, Colo. Democrat, could both be recalled. They will learn Tuesday whether attempts to oust them over their gun control measures were successful.

If Morse is recalled, Republican Bernie Herpin, the only candidate in on the same ballot, will succeed him. If Giron is recalled, she would be replaced by Republican George Rivera in the state Senate.

Early voting in Giron’s hometown began last Friday. As of Wednesday night, more than 3,500 people had already voted. Election officials told multiple members of the media that there were “surprisingly high turnouts,” in early voting.

Aggressive efforts to sway voters have been underway in the state by both the National Rifle Association and New York Mayor Michael Bloomberg’s Mayors Against Illegal Guns.
