One Nation, a top conservative group, is pushing a new ad against Sen. Jacky Rosen (D-Nev.) as it gears up for a campaign running through Labor Day against the Democratic incumbent.

The advertisement, part of a nearly $6 million buy, implores Rosen to “vote against reckless spending and for struggling Nevada families,” citing her votes for the infrastructure law and the Democratic social spending package.

Rosen faces GOP nominee — and Army veteran — Sam Brown in a competitive reelection bid in her swing state. Brown won his bid to take on the incumbent a week ago.

Outside money is flowing into the Silver State. Senate Majority PAC, Democrats’ largest outside group, placed $36 million in ad buys earlier this year to support Rosen.

The incumbent, a first-term senator from the Las Vegas suburb of Henderson, reported having more than $10 million in campaign cash on hand as of late May, compared with $2.5 million for Brown.
