A Democratic candidate attempting to unseat Speaker Paul Ryan (R-Wis.) mocked Republicans’ failure to pass a healthcare bill after they sent trackers to one of his events Tuesday.

“They (GOP) sent three trackers to the event tonight,” Randy Bryce, who is running in the Democratic primary for Ryan’s seat in Wisconsin, tweeted. “I hope they offer them health care.”

I hope they offer them health care.

Trackers are political operatives sent to follow opposing candidates, with the hopes of catching opponents making a mistake or learning more about their campaign operations.

{mosads}The Senate GOP faced a massive blow Tuesday after its bill to repeal and replace ObamaCare was killed by members of the party.

Senate Majority Leader Mitch McConnell (R-Ky.) said he will hold a vote on legislation solely repealing the bill early next week, but four Republican senators have already come out against it — enough to stop the measure from even reaching the Senate floor.

The House passed similar legislation in early May under Ryan’s leadership. No Democrats voted for the measure.

Bryce, who supported Sen. Bernie Sanders (I-Vt.) in the 2016 Democratic presidential primaries, has caught national attention for his campaign after the video announcing his candidacy went viral. Healthcare has been a major topic of his campaign so far.

He raised $430,000 during his campaign’s first 12 days and won the endorsement of his top Democratic rival, who has already dropped out of the race.
