The Latest: Leah Vukmir wins Wisconsin GOP Senate primary

MADISON, Wis. (AP) — The Latest on Wisconsin's primary election (all times local):

10 p.m.

The winner of Wisconsin's Republican primary for U.S. Senate says Republicans must now come together if they hope to defeat Democratic Sen. Tammy Baldwin.

State Sen. Leah Vukmir defeated political newcomer Kevin Nicholson on Tuesday.

Vukmir tells The Associated Press her win was a victory for the grass roots — which overwhelmingly backed her. She had the endorsement of the state party, while those supporting Nicholson outspent her by as much as $8 million.

Baldwin says if Republicans don't unite Baldwin will win.

Vukmir says to beat Baldwin she will emphasis "over and over again" where Baldwin has let the state down, including opposing President Donald Trump's nominees for the U.S. Supreme Court.

A state senator and close ally to Gov. Scott Walker has defeated a former Marine who cast himself as a political outsider in Wisconsin's Republican primary for U.S. Senate.

Leah Vukmir beat Kevin Nicholson in Tuesday's primary and now advances to face Democratic Sen. Tammy Baldwin.

Vukmir won the endorsement of the Wisconsin Republican Party and the backing of most prominent GOP officeholders, including House Speaker Paul Ryan. She ran as the proven conservative in the race, pointing to her long voting record in support of Republican priorities.

Both she and Nicholson ran as strong supporters of President Donald Trump.

Nicholson failed to overcome his past as a Democrat. He also lost despite millions more being spent on his behalf by outside groups.
