On a debate stage in New Hampshire earlier this month, Massachusetts Sen. Elizabeth Warren sought to draw a clear contrast between herself and other candidates on a hot-button issue — money in politics.

"Everyone on this stage except Amy (Klobuchar) and me is either a billionaire or is receiving help from PACs that can do unlimited spending," said Warren during the Feb. 7 debate.

But less than two weeks later, that statement is no longer true. 

In the past week, super PACs supporting Warren and Klobuchar have bought substantial television ad time in Nevada ahead of the state’s crucial presidential preference caucus on Saturday (Both Warren and Klobuchar's campaigns have said their positions on Super PACs have not changed).

Emergence of those two super PACs means that every major candidate competing in Nevada, save self-funded billionaire Tom Steyer, now has some kind of outside group or super PAC boosting their candidacy on television or radio airwaves in the state.

Super PACs are independent groups allowed under the U.S. Supreme Court decision in Citizens United v. FEC that are supposed to operate separately from official campaigns, but can raise and spend unlimited amounts of money. That means candidates can’t shut them down independently, though candidates and campaigns differ in how open they are to support from Super PACs.

Some candidates — such as Warren and Vermont Sen. Bernie Sanders — have publicly denounced super PAC support, while others have been more welcoming to outside boosts. Former Vice President Joe Biden reversed his opposition to super PAC support in October, and former South Bend Mayor Pete Buttigieg has already been subjected to a Federal Elections Commission complaint that his campaign improperly coordinated with a supportive super PAC (Buttgieg’s campaign has denied wrongdoing).

Even a super PAC supporting President Donald Trump — the Committee to Defend the President — is running TV ads in Nevada, designed to run during Wednesday’s debate and through the caucus.

The emergence of the outside spending is somewhat last minute and comes after more than 70,000 Nevada voters cast a ballot early under the state’s new system of allowing four days of early vote prior to the actual caucus. The spending is also far outstripped by Steyer, who has poured $15 million in TV ad spending into Nevada.

Former New York City Mayor Michael Bloomberg, who has already spent $338 million on advertising spending, is not competing in Nevada and does not have his name on the ballot. Even so, his team has still placed some television ad buys in the Reno area to hit California voters near the area, according to Axios, and many of his national television ad buys bleed into Nevada. 

Here’s a look at what outside groups and super PACs have made TV ad buys in Nevada ahead of the presidential caucus on Saturday:
